SFW - Simple Framework - https://github.com/Relintai/sfw
Simple c++ app / game framework inspired by the single file c game engines
and libraries, especially [FWK](https://github.com/r-lyeh/FWK).
**Modules**: Core, Object, Render Core, Render Immediate, Render Objects, GUI
COMPILE
====================================================================================
$FILE_Compilation_Renderer$
CORE
====================================================================================
Use SFWCore::setup(); to initialize the library.
This is necessary as some components (Like PoolVector, and StringNames.) need additional setup.
Use SFWCore::cleanup(); to de-initialize the library.
Note that if you use the Application class, it's constructor will do this for you automatically.
Also note that if you don't use classes that doens't rely on this you can get away by not calling it.

GUI::initialize(); to initialize the graphical user interface, and
to create the GUI singleton. (Will create an ImGUI context, and setup everything.)
Use GUI::destroy(); to deinitalize the graphical user interface, and
to delete the GUI singleton.
Call GUI::new_frame(); at the beginning of your frame to reset the gui's internal state.
Call GUI::render(); at the end of your frame to render your gui to the screen.
After the GUI singleton is initialized, you can use the built in Dear ImGUI library calls to create your user interface.

Dear ImGUI
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ C++
namespace ImGui
{
// Context creation and access
// - Each context create its own ImFontAtlas by default. You may instance one yourself and pass it to CreateContext() to share a font atlas between contexts.
// - DLL users: heaps and globals are not shared across DLL boundaries! You will need to call SetCurrentContext() + SetAllocatorFunctions()
// for each static/DLL boundary you are calling from. Read "Context and Memory Allocators" section of imgui.cpp for details.
ImGuiContext* CreateContext(ImFontAtlas* shared_font_atlas = NULL);
void DestroyContext(ImGuiContext* ctx = NULL); // NULL = destroy current context
ImGuiContext* GetCurrentContext();
void SetCurrentContext(ImGuiContext* ctx);
// Main
ImGuiIO& GetIO(); // access the ImGuiIO structure (mouse/keyboard/gamepad inputs, time, various configuration options/flags)
ImGuiPlatformIO& GetPlatformIO(); // access the ImGuiPlatformIO structure (mostly hooks/functions to connect to platform/renderer and OS Clipboard, IME etc.)
ImGuiStyle& GetStyle(); // access the Style structure (colors, sizes). Always use PushStyleColor(), PushStyleVar() to modify style mid-frame!
void NewFrame(); // start a new Dear ImGui frame, you can submit any command from this point until Render()/EndFrame().
void EndFrame(); // ends the Dear ImGui frame. automatically called by Render(). If you don't need to render data (skipping rendering) you may call EndFrame() without Render()... but you'll have wasted CPU already! If you don't need to render, better to not create any windows and not call NewFrame() at all!
void Render(); // ends the Dear ImGui frame, finalize the draw data. You can then get call GetDrawData().
ImDrawData* GetDrawData(); // valid after Render() and until the next call to NewFrame(). this is what you have to render.
// Demo, Debug, Information
void ShowDemoWindow(bool* p_open = NULL); // create Demo window. demonstrate most ImGui features. call this to learn about the library! try to make it always available in your application!
void ShowMetricsWindow(bool* p_open = NULL); // create Metrics/Debugger window. display Dear ImGui internals: windows, draw commands, various internal state, etc.
void ShowDebugLogWindow(bool* p_open = NULL); // create Debug Log window. display a simplified log of important dear imgui events.
void ShowIDStackToolWindow(bool* p_open = NULL); // create Stack Tool window. hover items with mouse to query information about the source of their unique ID.
void ShowAboutWindow(bool* p_open = NULL); // create About window. display Dear ImGui version, credits and build/system information.
void ShowStyleEditor(ImGuiStyle* ref = NULL); // add style editor block (not a window). you can pass in a reference ImGuiStyle structure to compare to, revert to and save to (else it uses the default style)
bool ShowStyleSelector(const char* label); // add style selector block (not a window), essentially a combo listing the default styles.
void ShowFontSelector(const char* label); // add font selector block (not a window), essentially a combo listing the loaded fonts.

void StyleColorsLight(ImGuiStyle* dst = NULL); // best used with borders and a custom, thicker font
void StyleColorsClassic(ImGuiStyle* dst = NULL); // classic imgui style
// Windows
// - Begin() = push window to the stack and start appending to it. End() = pop window from the stack.
// - Passing 'bool* p_open != NULL' shows a window-closing widget in the upper-right corner of the window,
// which clicking will set the boolean to false when clicked.
// - You may append multiple times to the same window during the same frame by calling Begin()/End() pairs multiple times.
// Some information such as 'flags' or 'p_open' will only be considered by the first call to Begin().
// - Begin() return false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting
// anything to the window. Always call a matching End() for each Begin() call, regardless of its return value!
// [Important: due to legacy reason, Begin/End and BeginChild/EndChild are inconsistent with all other functions
// such as BeginMenu/EndMenu, BeginPopup/EndPopup, etc. where the EndXXX call should only be called if the corresponding
// BeginXXX function returned true. Begin and BeginChild are the only odd ones out. Will be fixed in a future update.]
// - Note that the bottom of window stack always contains a window called "Debug".
bool Begin(const char* name, bool* p_open = NULL, ImGuiWindowFlags flags = 0);
void End();
// Child Windows
// - Use child windows to begin into a self-contained independent scrolling/clipping regions within a host window. Child windows can embed their own child.
// - Before 1.90 (November 2023), the "ImGuiChildFlags child_flags = 0" parameter was "bool border = false".
// This API is backward compatible with old code, as we guarantee that ImGuiChildFlags_Borders == true.
// Consider updating your old code:
// BeginChild("Name", size, false) -> Begin("Name", size, 0); or Begin("Name", size, ImGuiChildFlags_None);
// BeginChild("Name", size, true) -> Begin("Name", size, ImGuiChildFlags_Borders);
// - Manual sizing (each axis can use a different setting e.g. ImVec2(0.0f, 400.0f)):
// == 0.0f: use remaining parent window size for this axis.
// > 0.0f: use specified size for this axis.
// < 0.0f: right/bottom-align to specified distance from available content boundaries.
// - Specifying ImGuiChildFlags_AutoResizeX or ImGuiChildFlags_AutoResizeY makes the sizing automatic based on child contents.
// Combining both ImGuiChildFlags_AutoResizeX _and_ ImGuiChildFlags_AutoResizeY defeats purpose of a scrolling region and is NOT recommended.
// - BeginChild() returns false to indicate the window is collapsed or fully clipped, so you may early out and omit submitting
// anything to the window. Always call a matching EndChild() for each BeginChild() call, regardless of its return value.
// [Important: due to legacy reason, Begin/End and BeginChild/EndChild are inconsistent with all other functions
// such as BeginMenu/EndMenu, BeginPopup/EndPopup, etc. where the EndXXX call should only be called if the corresponding

// Layout cursor positioning
// - By "cursor" we mean the current output position.
// - The typical widget behavior is to output themselves at the current cursor position, then move the cursor one line down.
// - You can call SameLine() between widgets to undo the last carriage return and output at the right of the preceding widget.
// - YOU CAN DO 99% OF WHAT YOU NEED WITH ONLY GetCursorScreenPos() and GetContentRegionAvail().
// - Attention! We currently have inconsistencies between window-local and absolute positions we will aim to fix with future API:
// - Absolute coordinate: GetCursorScreenPos(), SetCursorScreenPos(), all ImDrawList:: functions. -> this is the preferred way forward.
// - Window-local coordinates: SameLine(offset), GetCursorPos(), SetCursorPos(), GetCursorStartPos(), PushTextWrapPos()
// - Window-local coordinates: GetContentRegionMax(), GetWindowContentRegionMin(), GetWindowContentRegionMax() --> all obsoleted. YOU DON'T NEED THEM.
// - GetCursorScreenPos() = GetCursorPos() + GetWindowPos(). GetWindowPos() is almost only ever useful to convert from window-local to absolute coordinates. Try not to use it.

// Read the FAQ (docs/FAQ.md or http://dearimgui.com/faq) for more details about how ID are handled in dear imgui.
// - Those questions are answered and impacted by understanding of the ID stack system:
// - "Q: Why is my widget not reacting when I click on it?"
// - "Q: How can I have widgets with an empty label?"
// - "Q: How can I have multiple widgets with the same label?"
// - Short version: ID are hashes of the entire ID stack. If you are creating widgets in a loop you most likely
// want to push a unique identifier (e.g. object pointer, loop index) to uniquely differentiate them.
// - You can also use the "Label##foobar" syntax within widget label to distinguish them from each others.
// - In this header file we use the "label"/"name" terminology to denote a string that will be displayed + used as an ID,
// whereas "str_id" denote a string that is only used as an ID and not normally displayed.

// - Use v_min < v_max to clamp edits to given limits. Note that CTRL+Click manual input can override those limits if ImGuiSliderFlags_AlwaysClamp is not used.

// Tooltips
// - Tooltips are windows following the mouse. They do not take focus away.

// Tooltips: helpers for showing a tooltip when hovering an item
// - BeginItemTooltip() is a shortcut for the 'if (IsItemHovered(ImGuiHoveredFlags_ForTooltip) && BeginTooltip())' idiom.
// - SetItemTooltip() is a shortcut for the 'if (IsItemHovered(ImGuiHoveredFlags_ForTooltip)) { SetTooltip(...); }' idiom.
// - Where 'ImGuiHoveredFlags_ForTooltip' itself is a shortcut to use 'style.HoverFlagsForTooltipMouse' or 'style.HoverFlagsForTooltipNav' depending on active input type. For mouse it defaults to 'ImGuiHoveredFlags_Stationary | ImGuiHoveredFlags_DelayShort'.

// - They block normal mouse hovering detection (and therefore most mouse interactions) behind them.

// - Their visibility state (~bool) is held internally instead of being held by the programmer as we are used to with regular Begin*() calls.
// - The 3 properties above are related: we need to retain popup visibility state in the library because popups may be closed as any time.
// - You can bypass the hovering restriction by using ImGuiHoveredFlags_AllowWhenBlockedByPopup when calling IsItemHovered() or IsWindowHovered().
// - IMPORTANT: Popup identifiers are relative to the current ID stack, so OpenPopup and BeginPopup generally needs to be at the same level of the stack.
// This is sometimes leading to confusing mistakes. May rework this in the future.
// - BeginPopup(): query popup state, if open start appending into the window. Call EndPopup() afterwards if returned true. ImGuiWindowFlags are forwarded to the window.
// - BeginPopupModal(): block every interaction behind the window, cannot be closed by user, add a dimming background, has a title bar.

// Popups: open/close functions
// - OpenPopup(): set popup state to open. ImGuiPopupFlags are available for opening options.
// - If not modal: they can be closed by clicking anywhere outside them, or by pressing ESCAPE.
// - CloseCurrentPopup(): use inside the BeginPopup()/EndPopup() scope to close manually.
// - CloseCurrentPopup() is called by default by Selectable()/MenuItem() when activated (FIXME: need some options).
// - Use ImGuiPopupFlags_NoOpenOverExistingPopup to avoid opening a popup if there's already one at the same level. This is equivalent to e.g. testing for !IsAnyPopupOpen() prior to OpenPopup().
// - Use IsWindowAppearing() after BeginPopup() to tell if a window just opened.
// - IMPORTANT: Notice that for OpenPopupOnItemClick() we exceptionally default flags to 1 (== ImGuiPopupFlags_MouseButtonRight) for backward compatibility with older API taking 'int mouse_button = 1' parameter

// - Helpers to do OpenPopup+BeginPopup where the Open action is triggered by e.g. hovering an item and right-clicking.
// - They are convenient to easily create context menus, hence the name.
// - IMPORTANT: Notice that BeginPopupContextXXX takes ImGuiPopupFlags just like OpenPopup() and unlike BeginPopup(). For full consistency, we may add ImGuiWindowFlags to the BeginPopupContextXXX functions in the future.

// Tables
// - Full-featured replacement for old Columns API.
// - See Demo->Tables for demo code. See top of imgui_tables.cpp for general commentary.
// - See ImGuiTableFlags_ and ImGuiTableColumnFlags_ enums for a description of available flags.
// The typical call flow is:
// - 1. Call BeginTable(), early out if returning false.
// - 2. Optionally call TableSetupColumn() to submit column name/flags/defaults.
// - 3. Optionally call TableSetupScrollFreeze() to request scroll freezing of columns/rows.
// - 4. Optionally call TableHeadersRow() to submit a header row. Names are pulled from TableSetupColumn() data.
// - 5. Populate contents:
// - In most situations you can use TableNextRow() + TableSetColumnIndex(N) to start appending into a column.
// - If you are using tables as a sort of grid, where every column is holding the same type of contents,
// you may prefer using TableNextColumn() instead of TableNextRow() + TableSetColumnIndex().
// TableNextColumn() will automatically wrap-around into the next row if needed.
// - IMPORTANT: Comparatively to the old Columns() API, we need to call TableNextColumn() for the first column!
// - Summary of possible call flow:
// - TableNextRow() -> TableSetColumnIndex(0) -> Text("Hello 0") -> TableSetColumnIndex(1) -> Text("Hello 1") // OK
// - TableNextRow() -> TableNextColumn() -> Text("Hello 0") -> TableNextColumn() -> Text("Hello 1") // OK
// - TableNextColumn() -> Text("Hello 0") -> TableNextColumn() -> Text("Hello 1") // OK: TableNextColumn() automatically gets to next row!
// - TableNextRow() -> Text("Hello 0") // Not OK! Missing TableSetColumnIndex() or TableNextColumn()! Text will not appear!
// - 5. Call EndTable()

// Tables: Headers & Columns declaration
// - Use TableSetupColumn() to specify label, resizing policy, default width/weight, id, various other flags etc.
// - Use TableHeadersRow() to create a header row and automatically submit a TableHeader() for each column.
// Headers are required to perform: reordering, sorting, and opening the context menu.
// The context menu can also be made available in columns body using ImGuiTableFlags_ContextMenuInBody.
// - You may manually submit headers using TableNextRow() + TableHeader() calls, but this is only useful in
