Ryan C. Gordon 3766a39409 emscripten: double the audio buffer size. 
Some systems seem to not keep up with the smaller buffer.

Reference Issue #11930.
 2025-01-13 16:26:18 -05:00
Ryan C. Gordon 2b8fb0bdd4 wikiheaders: Maybe fix perl warning.

Fixes #9044.
 2025-01-13 14:17:36 -05:00
Ryan C. Gordon 307e6f2ca6 emscripten: simulate mouse autocapture. 
This is just enough to delay MOUSE_LEAVE events until a drag ending outside
the canvas is released, and make sure the MOUSE_UP event has the canvas's
SDL_WindowID, which it wouldn't when mouse focus is was lost by this point.

Fixes #10033.
 2025-01-13 02:39:39 -05:00
Ryan C. Gordon 95c1584386 README-migration: note SDL2 brightness/gamma ramp APIs that have been removed.

Ryan C. Gordon f0af6c348a emscripten: Add SDL_EVENT_DISPLAY_ORIENTATION support. 
Reference Issue #11389.
 2025-01-12 02:23:00 -05:00
Ryan C. Gordon 3ad9c38a46 emscripten: Don't set OpenGL swap intervals until first PumpEvents. 
Any requested swap interval will be saved and set on the first PumpEvents.
Once PumpEvents has been called at least once, swap intervals are set
immediately.

This assumes that events won't be pumped until after an Emscripten main loop
has been defined, and so prevents a warning on the javascript console:

"emscripten_set_main_loop_timing: Cannot set timing mode for main loop since
a main loop does not exist! Call emscripten_set_main_loop first to set one
up."

Fixes #9969.

Reference PR #11900.
 2025-01-10 01:37:25 -05:00
Ryan C. Gordon 507593f485 wikiheaders: Allow symbols to be filtered from manpage generation by regex. 
This is specifically to prevent generating a manpage for "Uint32" and friends.

Fixes #11898.
 2025-01-09 14:13:00 -05:00
Ryan C. Gordon 3f7f632e14 audio: Added SDL_AudioDeviceStreamPaused. 
We had the other two wrapper functions to pause and resume, and forgot query.
 2025-01-09 01:36:57 -05:00
Ryan C. Gordon f61860fa93 testautomation: fixed incorrect test. 
The test was doing this:

- The output size is 80x60
- The logical size is 40x30
- The viewport is { 10, 7, 40, 30 }
- Draw to fill this whole viewport.

This would offset the filled rectangle a little, as before, but then the
viewport was the size of the entire logical space, so it wasn't a rectangle
centered in the middle of the output, as was expected.

This used to produce the expected output before the fix in
fa7a529912. But it appears the test was
incorrect, so this tweaks the viewport to produce the expected result.
 2025-01-08 23:33:39 -05:00
Ryan C. Gordon 4bb3c2a1c7 render: Some cleanups. 
Mostly setting NULL pointers to a local struct instead of copying non-NULL
pointers' contents into the local struct.
 2025-01-08 14:59:28 -05:00
Ryan C. Gordon 61bdbacdae render: SDL_RenderTextureTiled shouldn't try to drop draw calls, either. 2025-01-08 14:59:28 -05:00
Ryan C. Gordon f044a3d6ca Revert "render: GetRenderViewportSize shouldn't use scale, just logical presentation." 
This reverts commit ef758d05c1.

Turns out the bug in #11076 was that we were dropping texture draws
incorrectly, not that scale shouldn't be applied here. The dropped draw calls
were fixed in bf85320947, and this revert is
making the renderer consistent again.
 2025-01-08 14:59:27 -05:00
Ryan C. Gordon fa7a529912 render: GetRenderViewportSize shouldn't scale viewport dimensions. 
These are already scaled for the logical presentation (unless using the pixel
dimensions instead; we still scale those here).

Fixes #11704.
 2025-01-08 14:59:27 -05:00
Ryan C. Gordon bf85320947 render: Don't try to drop draws outside of the viewport. 
It didn't take scale into account, and the backends would need to do clipping
anyhow, so let the system figure that out for us at the lower level.

Fixes #11318.
 2025-01-08 11:55:10 -05:00
Ryan C. Gordon 6934c910b3 opengl: use GL_UNSIGNED_BYTE instead of GL_UNSIGNED_INT_8_8_8_8_REV. 
This seems to be significantly more efficient on some modern platforms, but if
this turns out to be a widespread disaster, we can revert it.
 2025-01-07 16:08:56 -05:00
Ryan C. Gordon 0180ca541e windows: Catch WM_POINTERCAPTURECHANGED events.

Ryan C. Gordon fa9c3331d5 main: Adjust how SDL_HINT_MAIN_CALLBACK_RATE works. 
Now (only in the generic backend, where it is implemented), this hint is
always respected. Previously it would only be used if no windows were created,
to help reduce CPU load on things like loopwave.

Since it's always used now, the default has changed from 60 (Hz) to 0 (run as
fast as possible). Things like loopwave should still likely force this way
lower than the previous default (and already do: loopwave explicitly sets it
to 5).

The hint can now also be set to "waitevent" which will cause SDL_AppIterate
to only be called after new events have arrived, for apps that are entirely
driven by input and want to consume (almost) no power or CPU time until then.

Fixes #11093.

Ryan C. Gordon d0d1414836 messagebox: Copy title and message up front, to protect SDL_GetError() strings. 
It's possible (likely!) someone could just pass a pointer returned by
SDL_GetError for one of these strings, but the message box code has to do a
ton of complicated stuff that might _also_ call SDL_SetError, so you could
end up with the string having different contents by the time you display it.

Just make a copy of the strings unconditionally at the start, so they're safe
no matter where they came from.
