vulkan: Combine textures and samplers again This reverts most of commit f420c143e0d8947a433704969bab02aea47d82f5 again because it turns out GPUs like combined images and samplers. But: The one thing we don't revert is allowing the C code to select any combination of sampler and image: gsk_vulkan_render_get_image_descriptor() now takes a 2nd argument specifying the sampler. This allows the same flexibility as before, we just combine things early. This change was inspired by https://developer.nvidia.com/blog/vulkan-dos-donts/ 2023-06-28 18:50:43 +00:00			`layout(set = 0, binding = 0) uniform sampler2D textures[50000];`
			`layout(set = 1, binding = 0) readonly buffer FloatBuffers {`
vulkan: Add support for storage buffers And add a default storage buffer that is used for per-frame temporary data. So far nothing is using this code, this is just infrastructure. 2023-05-25 20:21:23 +00:00			`float floats[];`
			`} buffers[50000];`
vulkan: Split textures and samplers The idea here is that we can do more complex combinations and use that to support texture-scale nodes or use fancy texture formats (suc as YUV). I'm not sure this is actually necessary, but for now it gives more flexibility. 2023-05-23 03:08:13 +00:00
