9ccdaa49f4 Removed reference to icon-alpha.bmp 
This file was never added, and I believe this just had a 50% alpha channel added to the standard icon.bmp

cd6b68a9fb Define the behavior of a negative width or height passed to SDL_RenderFillRect() 
The software renderer now matches the 3D renderer behavior by rendering a reversed rectangle (extending width or height in the opposite direction) when width or height is negative. It also now renders no rectangle if the width and height are 0.

2a0e751ff5 gamepad: Fixed Emscripten guide button, after recent changes. 
(buttons above 12 all shifted down by four, since the dpad buttons now look
like a hat...the only one above the dpad buttons on a standard layout is the
guide button, index 16. This change moves it to 12.)

937bf4d789 alsa: Restart PCM devices after recovery from an overrun/underrun. 
snd_pcm_recover() puts the device back in SND_PCM_STATE_PREPARED state; you
have to explicitly restart the device afterwards with snd_pcm_start().

Fixes #13761.

b8197a2291 io: rework how we set SDL_IOStream status. 
This now relies on the implementation to set these flags on short reads/writes
instead of the higher level checking if SDL_SetError() was called.

Additionally (and crucially), this now sets ERROR or EOF on all short reads,
across all backends, not just when we get a zero-byte return value.

Fixes #13720.

99da009308 wikiheaders: Escape backslash in man pages 
Otherwise, groff will interpret it as a macro, causing the man page
for SDL_GetPrefPath() to be mis-rendered. Escape unescaped backslashes
as `\(rs` ("reverse solidus") before escaping other characters with
macros that, themselves, contain backslashes.

Resolves: https://github.com/libsdl-org/SDL/issues/13039

3597877277 SDL_main.h: Cleanups in SDL_RegisterApp documentation. 
There is an escaped pipe character, because this ends up in a Markdown table
on the wiki, and the wiki software (incorrectly, I think) sees the pipe inside
a code-block and thinks it's the end of the table cell if not escaped.

But this escape char looks wrong everywhere else.

Keeping the parameter table terse is always a good idea, so I moved the
detail out to the Remarks section, which doesn't have a problem with this
character appearing in the text.
