Sam Lantinga cc2a272d6f Enable RLE more often in the software renderer 
We don't need to aggressively disable RLE acceleration anymore because the original pixels remain available for operations that aren't supported by the RLE blitter.
 2025-11-08 14:51:27 -08:00
Sam Lantinga ac0edbe9d2 Just assert that RLE encoding isn't active 
We undo RLE encoding in the calling code, so we shouldn't need to do anything here.

Sam Lantinga 2b365983db Save the original pixels when RLE encoding is enabled 
Trying to reconstruct the original image when undoing RLE encoding was never completely accurate.

Chris Genova 6a01d6e7d3 D3D12 GPU: Prevent reading out of bounds when uploading textures.
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled
Build (All) / level2 (push) Has been cancelled 
When the upload needs realignment, a new buffer is created to do the
upload, and the source data is copied to the new buffer. This commit
fixes the issue where the memcopy can read off the end of the source
buffer since it is reading based on destination pitch instead of source
pitch.

Frank Praznik 950a9a72ab wayland: Use a pool to allocate icon image buffers 
Allocate the buffers from a pool to avoid a separate mmap for each image.

Frank Praznik b3060956c3 wayland: Release the SHM pool after initial cursor buffer creation 
The backing memory will be automatically unmapped when the buffer objects are destroyed, so no need to keep the pool around.

Sam Lantinga 118dcf27ce Added D mode mappings for the 8BitDo 64 Bluetooth Controller 
The HID descriptor maps the C buttons as a right thumbstick, but this mapping matches the HIDAPI Nintendo 64 mapping.

The start button resets the controller in both USB and Bluetooth mode on macOS, but I've kept the mapping assuming this is a macOS bug that will be fixed.

Frank Praznik a71b2f0a93 x11: Only correct placement for border offset on the initial window mapping
Build (All) / Create test plan (push) Has been cancelled
Build (All) / level1 (push) Has been cancelled

Correcting it when it is subsequently hidden and re-mapped will cause the position to be double offset by the size of the borders.

Sam Lantinga 4560fae07e Fail configuration if X11 dependency packages aren't available 
It happens fairly often that people enable X11 support but don't install the extension libraries that SDL depends on. This makes those required if not explicitly disabled, which should help prevent accidentally broken builds.
