1cda789a37 render: Default to primary display in SDL_CalculateSimulatedVSyncInterval if window is not set 
- Fixes previous change to SDL_CreateRendererWithProperties which skipped SDL_CalculateSimulatedVSyncInterval if window was not set.

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 
When the application modifies the palette, any textures that use it will automatically be updated.

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

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.

8aa5b97bb5 renderer: Always use the output size when updating the main view 
The main view always reflects the size of the output, so don't use the dimensions of the currently bound render target texture when updating it, or it will reflect an incorrect size when the render target texture is unbound.

5d20bbf348 Presenting while drawing to a render target should fail. 
People are adding present calls while rendering to render targets, not understanding that this doesn't make sense, and wondering why they get flicker on some systems. If there are programs that relied on the previous behavior we can add a hint to control this.
