32668c4ddd Palettized textures will always use SDL_SCALEMODE_NEAREST. 
Our algorithm for pixel art doesn't work on 8-bit images, needs further investigation.

a864dcac25 Added support for using the GPU renderer as an offscreen renderer 
SDL_CreateGPURenderer() now allows passing in an existing GPU device and passing in a NULL window to create an offscreen renderer.

Also renamed SDL_SetRenderGPUState() to SDL_SetGPURenderState().

b65590159b Each application palette corresponds to one hardware palette

2a01e12d34 Simplify palette code 
Each texture gets its own palette, the palette is updated when it is rendered if necessary, rendering is flushed if a texture render is already queued up.

Trying to share palettes and handle the different cases of queued rendering and changing palettes in the middle of the frame ends up being very complicated, so we'll keep it simple for now.

ee1c90a358 Improved handling of function parameter validation 
SDL supports the following use cases:
 * Normal operation with fast parameter checks (default):
    SDL_SetHint(SDL_HINT_INVALID_PARAM_CHECKS, "1");
 * Object parameters are checked for use-after-free issues:
    SDL_SetHint(SDL_HINT_INVALID_PARAM_CHECKS, "2");
 * Enable full validation, plus assert on invalid parameters:
    #define SDL_ASSERT_INVALID_PARAMS
 * Disable all parameter validation:
    #define SDL_DISABLE_INVALID_PARAMS

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.

152ba829a1 video: Try to reconfigure the window for OpenGL without destroying it 
When attaching a renderer (GL based specifically) to a window that was not created with the appropriate flags, the window would be destroyed and recreated to configure it for the desired rendering backend. While most of the issues with this have been mitigated over time, there can still be some undesirable side effects from doing so on certain platforms.

If the window was just created and was never configured for any graphics context, it is possible that the reconfiguration can be done without destroying the window first.

The Wayland implementation fixes an issue when creating a window with the fullscreen flag on wlroots based Wayland compositors, and can likely be extended to other platforms to avoid unnecessarily destroying/recreating a window in the very common case where a window is created, followed immediately by attaching a renderer.

07ef532681 hints: Renamed SDL_HINT_LOG_BACKENDS to SDL_DEBUG_LOGGING. 
This still logs backend choices, but we might use it for other things. For
example, what Android device is being used, or all the devices we enumerated,
etc.

Ideally this eventually logs all the stuff we often have to ask followup
questions about.
