Looking through the code for SDL_GetPlatform(), it is obvious that the case for
Android platform doesn't exist. And hence SDL_GetPlatform() doesn't return a
useful string on Android Phones.
It's a long-dead platform, and we don't have any way to build for, test, or
maintain it, so there's no sense in doing acrobatics to support it.
If you need Windows CE support, use SDL 1.2. If you need Windows Phone support,
send SDL 2.0 patches for the newer Windows Mobile platform.

Background: X has two main 'buffers' for copy/paste:
PRIMARY -- normally used for implicit selection of text, with middle-click to
paste
CLIPBOARD -- works with an explicit copy/paste like on other platforms.
Currently SDL2 only provides access to PRIMARY. Since CLIPBOARD is much closer
to functionality of other platforms, SDL should provide access to that instead.
The attached patch makes it so that SDL_SetClipboardText() sets both PRIMARY
and CLIPBOARD and SDL_GetClipboardText() reads from CLIPBOARD instead of
primary.
Hello Sam,
while profiling ScummVM I noticed it was making use of the generic
BlitNToN blitter, which struck me as odd because it should be a very
classical codepath.
After investigating, I saw that in the blit op chooser:
{ 0x0000F800,0x000007E0,0x0000001F, 4, 0x00FF0000,0x0000FF00,0x000000FF,
0, NULL, Blit_RGB565_ARGB8888, SET_ALPHA },
{ 0x0000F800,0x000007E0,0x0000001F, 4, 0x000000FF,0x0000FF00,0x00FF0000,
0, NULL, Blit_RGB565_ABGR8888, SET_ALPHA },
{ 0x0000F800,0x000007E0,0x0000001F, 4, 0xFF000000,0x00FF0000,0x0000FF00,
0, NULL, Blit_RGB565_RGBA8888, SET_ALPHA },
{ 0x0000F800,0x000007E0,0x0000001F, 4, 0x0000FF00,0x00FF0000,0xFF000000,
0, NULL, Blit_RGB565_BGRA8888, SET_ALPHA },
Couldn't the optimized versions be used for NO_ALPHA too? I take it
that the resulting alpha component can be undefined as it should never
be used.
I tried this (see attached patch) and it worked perfectly (and
therefore faster) on ScummVM but there might be a trick (I'm not
expert at the semantics of SDL, ie NO_ALPHA, SET_ALPHA and COPY_ALPHA
there).
What do you think?
Cheers,
Bertrand

The attached patch from the OpenBSD ports tree is to increase the number of
uhid devices to scan for joysticks. It's somewhat easy to exhaust the default
number of devices which are scanned.

With OpenGL 4.3 the ARB added a new context flag for context reset isolation
and renamed the existing ES2 profile bit to ES profile bit, as it can be used
to request GLES 3 compatible contexts, too.
This patch adds these changes to SDL on Linux and Windows.
Also SDL lacks the ability to create shared contexts. This patch also adds a
new GL attribute to enable context sharing. As casting a GL context to int is
not portable, I added only a boolean attribute
SDL_GL_SHARE_WITH_CURRENT_CONTEXT, which makes the new context share resources
with the context current on the creating thread.
I think you'll need to install Xquartz, the external-but-official replacement
for Apple's X11, to get the Xlib headers: http://support.apple.com/kb/HT5293
