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.

b99ff00a95 Removed logic forcing vsync on if setting it off fails
The platforms that needed this (Windows Phone and Windows RT) are no longer supported, and if this is needed in the future it should be done at the renderer level, not here.

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.

c922762791 proposed fix: set curr_src.h is to bottom_height before drawing bottom edges / corners in SDL_RenderTexture9Grid, to avoid issue where inadvertently using top height if the npatch existed on a larger texture than the drawn edge would cause too many pixels to be included in the bottom part of the render. 2025-02-01 16:09:08 -08:00
