- Always use internal qsort and bsearch implementation.
- add "_r" reentrant versions.
The reasons for always using the internal versions is that the C runtime
versions' callbacks are not mark STDCALL, so we would have add bridge
functions for them anyhow, The C runtime qsort_r/qsort_s have different
orders of arguments on different platforms, and most importantly: qsort()
isn't a stable sort, and isn't guaranteed to give the same ordering for
two objects marked as equal by the callback...as such, Visual Studio and
glibc can give different sort results for the same data set...in this
sense, having one piece of code shared on all platforms makes sense here,
for reliabillity.
bsearch does not have a standard _r version at all, and suffers from the
same SDLCALL concern. Since the code is simple and we would have to work
around the C runtime, it's easier to just go with the built-in function
and remove all the CMake C runtime tests.
Fixes#9159.
* Make sure to always write pointSize in VS (fixes validation error in testsprite)
* Fix validation error from acquiring swapchain semaphore more than once
* Fix validation error from using incorrect framebuffer size in testautomation
Now passes testautomation with validation.
* Vulkan Renderer - implement YcBcCr using VK_KHR_sampler_ycbcr_conversion. This simplifies the shader code and will also allow support for additional formats that we don't yet support (such as SDL_PIXELFORMAT_P010 for ffmpeg). The renderer now queries for VK_KHR_sampler_ycbcr_conversion and dependent extensions and will enable it if it's present. It reimplements YUV/NV12 texture support using this extension (these formats are no longer supported if the extension is not present). For each YUV/NV12 texture, a VkSamplerYcbcrConversion object is created from SDL_Colorspace parameters. This is passed to the VkImageView and also an additional sampler is created for Ycbcr. Instead of using 1-3 textures, the shaders now all use 1 texture with a combined image sampler (required by the extension). Further, when using Ycbcr, a separate descriptor set layout is baked with the Ycbcr sampler as an immutable sampler. The code to copy the images now copies to the individual image planes. The swizzling between formats is handled in the VkSamplerYcbcrConversion object.
The removal of a wl_output may not be accompanied by leave events for the surfaces present on it. Ensure that no window continues to hold a reference to a removed output.
