The _xgetbv intrinsic was being used in ARM builds of SDL/WinRT, which was
leading to linker errors.  This commit limits _xgetbv use to the platforms on
which it is available, x86 and x64.

Subject: [PATCH 20/50] Haptic: Fix the saturation and deadband parameters'
 available range.

There was a misconception that Linux's saturation and deadband parameters -
on which the corresponding SDL parameters were based - use only half of the
possible range.

Thanks, Elias!

Subject: [PATCH 26/50] Fixed bug 2687 - SDL_BlitScaled does not handle
 clipping correctly

Patch from Benoit Pierre:

video: fix clipping handling in SDL_UpperBlitScaled

- honor destination clipping rectangle
- update both destination and source rectangles when clipping source
  rectangle to source surface and destination rectangle to destination
  clip rectangle
- don't change scaling factors when clipping

N.B.:

- when no scaling is involved (source and destination width/height are
  the same), SDL_UpperBlit is used (so SDL_BlitScaled behaves like
  SDL_BlitSurface)
- the final destination rectangle after all clipping is performed is
  saved back to dstrect (like for SDL_UpperBlit)

Subject: [PATCH 27/50] Fixed bug 2683 - Raspberry PI support using CMake

Tobias Himmer

this patch adds a check to the CMake build script to detect whether the VideoCore API is available.
If it is found, it enables SDL_VIDEO_DRIVER_RPI and will also add the needed include/library directory flags to CMAKE_C_FLAGS so the subsequent check for GLES succeeds in picking up the headers.

Seems to work fine on Raspbian.

Subject: [PATCH 28/50] Fixed bug 2681 - dereference a NULL pointer dst_fmt in
 SDL_CreateTextureFromSurface function

Nitz

In SDL_CreateTextureFromSurface:

SDL_PixelFormat *dst_fmt;
/* Set up a destination surface for the texture update */
         dst_fmt = SDL_AllocFormat(format);
            temp = SDL_ConvertSurface(surface, dst_fmt, 0);

Here is need of NULL check for dst_fmt because there are chances of NULL return from SDL_AllocFormat(format);

Subject: [PATCH 35/50] Fixed bug 2685 - SDL_RenderReadPixels() doesn't work
 with offscreen targets

Andreas Falkenhahn

SDL_RenderReadPixels() doesn't seem to work when trying to read pixels from a texture that has been created using SDL_TEXTUREACCESS_TARGET and has been selected as the render target using SDL_SetRenderTarget().

I am attaching a small program that demonstrates the issue. I get the following result here:

READ PIXEL RETURN: 0 --- COLOR CHECK: ff000000

But it should be:

READ PIXEL RETURN: 0 --- COLOR CHECK: ffff0000

Tested with SDL 2.0.3 on Windows 7.

Subject: [PATCH 36/50] Fixed bug 2655 - OSX: Window position and global mouse
 coord spaces are different

Tim McDaniel

On OSX, with revision 8729, the coordinate space for window position and the coordinate space for global mouse position don't match.  For a non-fullscreen window, the window position is global relative to the bottom of the menubar.  The global mouse position is relative to the top of the screen.  This affects Cocoa_WarpMouse and potentially other things as well.  Further, the coordinate system for window position is now affected by what screen it is on.  For example, if I have two equal size screens oriented side by side such that the tops of the screens are equal in global space, with the menubar on one screen, and a window straddles the two screens, the window's y position makes no sense.  The window's y position depends on what screen "most" of the window is on.  So if I move the window horizontally just a bit, the y position of my window is now different by the size of the menubar, even though the window was not moved vertically.

I'd like to reiterate that this was a fairly fundamental change (and a breaking change for us).  If SDL OSX is to really support multi-display configurations, this is especially problematic.

If the real concern is preventing windows from going under the menubar, then perhaps a solution involving something like overriding [NSWindow constrainFrameRect] would be less problematic than redefining the global window coord space for the main display.

Subject: [PATCH 37/50] Fixed 2680 - OSX: Replace NSAutoreleasePool with
 @autoreleasepool

Tim McDaniel

This patch replaces all use of NSAutoreleasePool with the Apple recommended @autoreleasepool.  @autoreleasepool is supposedly more efficient, and since it is scope based it can't be accidentally not released.

Subject: [PATCH 44/50] Fixed bug 2694 - configure bug __has_feature macro not
 detected

skaller

using gcc 4.2 (the default) on Mac OSX 10.6.8

 CC     build/SDL_dynapi.lo
In file included from /Users/johnskaller/SDL/src/dynapi/SDL_dynapi.c:31:
include/SDL_syswm.h:211:39: error: missing binary operator before token "("

The fault appears to be here:

#if defined(__OBJC__) && __has_feature(objc_arc)

that the __has_feature macro is not supported by gcc 4.2.

The code works fine with my clang 3.3svn.

Subject: [PATCH 47/50] Add a SDL_IM_INTERNAL_EDITING event to make IMs like
 iBus render editing text in its own UI instead of sending TEXTEDITING events.
 This is useful for applications that handle TEXTINPUT events but not
 TEXTEDITING events.

 default.

The configure script fails on it on Mac OS X, now, for whatever reason.

Hopefully gets our static analysis buildslave running again!
