Apparently you might get strange paths from GetModuleFileName(), such as
short path names or UNC filenames, so this avoids that problem. Since you have
to tapdance with linking different libraries and defining macros depending on
what Windows you plan to target, we dynamically load the API we need, which
works on all versions of Windows (on Win7, it'll load a compatibility wrapper
for the newer API location).
What a mess.
This also now does the right thing if there isn't enough space to store the
path, looping with a larger allocated buffer each try.

Currently the keymapnotify event handling is commented out as FIXME in SDL_x11events.c (It looks like this may have functioned SDL1.2).
Not handling this event means that if a window manager shortcut such as ALT+SPACE is used, SDL will send an ALT key down signal, but not an up signal. Also querying SDL about the key state, it believes the ALT key remains pressed.
X passes the events keypress (alt), ?focusout?, ?focusin?, keymapnotify.
If SDL_SaveBMP_RW() was called with NULL passed as SDL_RWops argument, different
values were returned depending on SDL_GetError(). If no error was set before the
call (or SDL_ClearError() was called) then 0 was returned. This is wrong because
nothing was saved. If an error was set before the call then -1 was returned.
This was fixed by directly returning -1 for NULL input instead of deciding based
on SDL_GetError(). No new error is set because this would otherwise override a
maybe more useful error set in SDL_RWFromFile() which is used by SDL_SaveBMP().

Notable changes, from Alex's notes:
- The SDL_WINDOW_ALLOW_HIGHDPI flag is now needed (along with SDL_GL_GetDrawableSize or SDL_GetRendererOutputSize) to use Retina / high DPI resolutions, bringing SDL?s Retina-related behavior on iOS in line with Mac OS X. Window dimensions and display modes are now in the ?points? (non-high DPI) coordinate system rather than pixels, whereas SDL_GL_GetDrawableSize is in pixels.
- Reworked the custom extended launch screen code:
- It now hides after the first SDL_PumpEvents call rather than SDL_CreateWindow, and it fades out in a similar manner to the system launch screen behavior.
- It now mirrors the system launch screen behavior when deciding which image to display: it falls back to using the Launch Images dictionary in Info.plist if the iOS 8+ launch screen nib isn?t available, and if the Launch Images dictionary doesn?t exist it uses the old standard launch image names.
- The extended launch screen can now be disabled via the SDL_IPHONE_LAUNCHSCREEN define in SDL_config_iphoneos.h.
- Added support for SDL_HINT_ACCELEROMETER_AS_JOYSTICK.
- Added access to a window view's renderbuffer and framebuffer to syswm.
- Added OpenGL ES debug labels for the Renderbuffer and Framebuffer Objects created with SDL_GL_CreateContext.
- Added support for sRGB OpenGL ES contexts on iOS 7+.
- Updated OpenGL ES contexts to support native-resolution rendering (when SDL_WINDOW_ALLOW_HIGHDPI is enabled) on the iPhone 6 Plus, i.e. 1080x1920 rather than 1242x2208.
- Updated SDL_GL_CreateContext, SDL_GL_SwapWindow, SDL_GL_MakeCurrent, and SDL_GL_DeleteContext to be more robust.
- Updated SDL windows to display a UIView at all times, even when an OpenGL context is not active. This allows rotation, touch events, and other windowing-related events to work properly without an active OpenGL context. It also makes it easier to use SDL_GetWindowWMInfo after creating a SDL window.
- Updated the iOS-specific Objective-C code to use cleaner and more modern language features and APIs, including ARC instead of manual reference counting.
- Updated SDL_HINT_ORIENTATIONS to allow disabling custom orientations if the hint is set with no valid orientation names.
- Fixed several rotation and orientation bugs with windows and display modes, especially in iOS 8+.
- Fixed SDL_SetWindowFullscreen failing to update the status bar visibility on iOS 7+.
- Fixed the orientation of the offset applied to the window?s view when the onscreen keyboard is shown in iOS 8+.
- Fixed SDL_IsScreenKeyboardShown (patch by Phil Hassey.)
- Fixed several major memory leaks caused by missing autorelease pool blocks in the iOS-specific Objective-C code.
- Removed several dead code paths.
- The iOS 7 SDK (Xcode 5) or newer is now required to build SDL for iOS.
