Sam Lantinga b65590159b Each application palette corresponds to one hardware palette 
When the application modifies the palette, any textures that use it will automatically be updated.

Sam Lantinga b82b1f416f Fixed Vulkan validation error 
VUID-VkPipelineRasterizationStateCreateInfo-depthClampEnable-00782(ERROR / SPEC): msgNum: -316906200 - Validation Error: [ VUID-VkPipelineRasterizationStateCreateInfo-depthClampEnable-00782 ] | MessageID = 0xed1c6528 | vkCreateGraphicsPipelines(): pCreateInfos[0].pRasterizationState->depthClampEnable is VK_TRUE, but the depthClamp feature was not enabled. The Vulkan spec states: If the depthClamp feature is not enabled, depthClampEnable must be VK_FALSE (https://vulkan.lunarg.com/doc/view/1.3.268.0/windows/1.3-extensions/vkspec.html#VUID-VkPipelineRasterizationStateCreateInfo-depthClampEnable-00782)

Sam Lantinga 524ba0a4ad Reduce the size of the D3D12 vertex shader constants 
This is needed to add more fragment shader constants in the future as we're already at our 64 size limit

Sam Lantinga 5622eef5a8 Fixed memory leak if requested renderer isn't available 2025-09-28 22:10:06 -07:00
Sam Lantinga 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.

Sam Lantinga b2188b325d Fixed HIDAPI controller disconnect reading on multiple threads 
If multiple threads are calling SDL_UpdateJoysticks(), then an overlapped read can be initiated on one thread (read_pending set to true) and GetOverlappedResult() called on another thread. This results in ERROR_OPERATION_ABORTED. This is harmless so we shouldn't return an error in this case, we'll just retry the read on the next call.

Sam Lantinga 26dd4e3abb Fixed filesystem operations on Android 
Full paths are used as-is, relative paths are prepended with SDL_GetAndroidInternalStoragePath(), and operations fall back to the asset system as appropriate.

This is consistent with the behavior of opening files on Android.

Sam Lantinga 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

Sam Lantinga f8bace9b9b Remove the behavior of warping the mouse on fullscreen transitions 
This made sense when switching between a window and an exclusive fullscreen video mode of the same dimensions, but it causes user confusion when the window changes size, and doesn't work well with Wayland. I've gotten this feedback from several sources, so we'll just go ahead and remove this behavior for now.
