block_compression

Texture block compression using WGPU compute shader. The shaders are a port of Intel's ISPC Texture Compressor's kernel to WGSL compute shader.

Tested with the following backends:

• DX12
• Metal
• Vulkan

Supported block compressions

Currently supported block compressions are:

• BC1
• BC2
• BC3
• BC4
• BC5
• BC6H
• BC7

DX12 pipeline creation

The pipeline creation for BC7 and especially BC6H takes a long time under DX12. The DXC compiler seems to take a very long time to compile the shader. For this reason we moved them behind features, which are included in the default features.
