6a3ad8a998 Fixed bug 2367 - Bad mouse motion coordinates with two windows where one has changed logical size
Andreas Ragnerstam

I have two windows where one has a renderer where the logical size has been changed with SDL_RenderSetLogicalSize. When I get SDL_MOUSEMOTION events belonging to the non-scaled window these will have been scaled with the factor of the scaled window, which is not expected.

Adding some printf debugging to SDL_RendererEventWatch of SDL_render.c, where (event->type == SDL_MOUSEMOTION), I found that for every mouse motion SDL_RendererEventWatch is called twice and the event->motion.x and event.motion.y are set twice for the event, once for each renderer where only the last one set will be saved to the event struct. This will work fine if both renderers have the same scale, but otherwise the motion coordinates will be scaled for the renderer belonging to another window than the mouse was moved in.

I guess one solution would be to check that window == renderer->window for SDL_MOUSEMOTION events, similar to what is done for when SDL_WINDOWEVENT events.

I get the same error on both X11 and Windows.
The same problem also exists for SDL_MOUSEBUTTONDOWN and SDL_MOUSEBUTTONUP events.

25abce513d WinRT: added Win10/UWP (Universal Windows Platform) support
"UWP" appears to be Microsoft's new name for WinRT/Windows-Store APIs.

This set of changes updates SDL's WinRT backends to support the Win10 flavor
of WinRT.  It has been tested on Win10 on a desktop.  In theory, it should
also support Win10 on other devices (phone, Xbox One, etc.), however further
patches may be necessary.

This adds:
- a set of MSVC 2015 project files, for use in creating UWP apps
- modifications to various pieces of SDL, in order to compile via MSVC 2015 +
  the Win10 API set
- enables SDL_Window resizing and programmatic-fullscreen toggling, when using
  the WinRT backend
- WinRT README updates

623898f70b WinRT: lots of display and windowing related fixes
This change-set fixes a lot of windowing related bugs, especially with
regards to Windows 8.x apps running on Windows 10 (which was the driver for
this work).  The primary fixes include:
* listed display modes were wrong, especially when launching apps into a
  non-fullscreen space
* reported window flags were often wrong, especially on Windows 10
* fullscreen/windowed mode switches weren't failing (they are not
  programmatically possible in Win 8.x apps).

4c72d39ce7 D3D11: Fixed SDL_RenderDrawPoints() ignoring input after the first 128 points.

0e45984fa0 Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

78f3a80cf2 WinRT: made note that VSync is always enabled on WinPhone, due to OS
Windows Phone does not appear to allow VSync to be turned off.  Doing so appears
to either result in content not getting drawn (when the D3D debug runtime is
turned off), or forcing VSync back on and logging an error (when the D3D debug
runtime is turned on).

VSync had been getting turned on anyways, this change just notes such:
- via the WinRT README
- by always setting the SDL_RENDERER_PRESENTVSYNC flag when creating an
  SDL_Renderer on Windows Phone

b48e54aafe Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation
Jonas Kulla

The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.

I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

fe40a17224 Initial merge of Emscripten port!
With this commit, you can compile SDL2 with Emscripten
( http://emscripten.org/ ), and make your SDL-based C/C++ program
into a web app.

This port was due to the efforts of several people, including: Charlie Birks,
Sathyanarayanan Gunasekaran, Jukka Jyl?nki, Alon Zakai, Edward Rudd,
Bruce Mitchener, and Martin Gerhardy. (Thanks, everyone!)

313881175d Adds support to control the scaling policy/mode of SDL_RenderSetLogicalSize for both letterbox (current behavior) and a new overscan mode (expand to fill the entire screen, even if some parts draw off the screen).
The expected use case is for games that are designed with multiple aspect ratios already in mind and leave optional margins on the edges of the game which won't hurt if they are cut off.

An example use case is a game is designed for wide-screen/16:9, but then wants to deploy on an iPad which is 4:3. Normally, SDL will letterbox, which will shrink things and result in wasted space. But the designer already thought about 4:3 and designed the edges of the game so they could be cut off without any functional loss. So rather than wasting space with letterboxing, "overscan" mode will zoom the rendering to fill up the entire screen. Parts on the edges will be drawn offscreen, but since the game was already designed with this in mind, it is fine. The end result is the iPad (4:3) experience is much better since it feels like a game designed for that screen aspect ratio.

This patch introduces a new SDL_hint: SDL_HINT_RENDER_LOGICAL_SIZE_MODE.
Valid values are "letterbox" or "0" for letterboxing and "overscan" or "1" for overscan.
The default mode is letterbox to preserve existing behavior.

// Example usage:
SDL_SetHint(SDL_HINT_RENDER_LOGICAL_SIZE_MODE, "overscan");
SDL_RenderSetLogicalSize(renderer, SCREEN_WIDTH, SCREEN_HEIGHT);

70438be272 WinRT: fixed bug whereby SDL would override an app's default orientation
WinRT apps can set a default, preferred orientation via a .appxmanifest file.
SDL was overriding this on app startup, and making the app use all possible
orientations (landscape and portrait).

Thanks to Eric Wing for the heads up on this!

20a6c623c3 WinRT: fixed bug whereby offscreen-rendered content could get improperly rotated
Attributes on the host device's rotation were getting applied to offscreen
textures in an invalid manner.  This was causing some apps to look different,
depending on how the device was rotated.

24c86b5501 [X11] Reconcile logical keyboard state with physical state on FocusIn
since the window system doesn't do it for us like other platforms.

This prevents sticky keys and missed keys when going in and out
of focus, for example Alt would appear to stick if switching away
from an SDL app with Alt-Tab and had to be pressed again.

b72938c861 Windows: Always set the system timer resolution to 1ms by default.
An existing hint lets apps that don't need the timer resolution changed avoid
this, to save battery, etc, but this fixes several problems in timing, audio
callbacks not firing fast enough, etc.

Fixes Bugzilla #2944.
