Support array / cubemap / cubemap array textures in KTX2 (#5325) # Objective - Fix / support KTX2 array / cubemap / cubemap array textures - Fixes #4495 . Supersedes #4514 . ## Solution - Add `Option<TextureViewDescriptor>` to `Image` to enable configuration of the `TextureViewDimension` of a texture. - This allows users to set `D2Array`, `D3`, `Cube`, `CubeArray` or whatever they need - Automatically configure this when loading KTX2 - Transcode all layers and faces instead of just one - Use the UASTC block size of 128 bits, and the number of blocks in x/y for a given mip level in order to determine the offset of the layer and face within the KTX2 mip level data - `wgpu` wants data ordered as layer 0 mip 0..n, layer 1 mip 0..n, etc. See https://docs.rs/wgpu/latest/wgpu/util/trait.DeviceExt.html#tymethod.create_texture_with_data - Reorder the data KTX2 mip X layer Y face Z to `wgpu` layer Y face Z mip X order - Add a `skybox` example to demonstrate / test loading cubemaps from PNG and KTX2, including ASTC 4x4, BC7, and ETC2 compression for support everywhere. Note that you need to enable the `ktx2,zstd` features to be able to load the compressed textures. --- ## Changelog - Fixed: KTX2 array / cubemap / cubemap array textures - Fixes: Validation failure for compressed textures stored in KTX2 where the width/height are not a multiple of the block dimensions. - Added: `Image` now has an `Option<TextureViewDescriptor>` field to enable configuration of the texture view. This is useful for configuring the `TextureViewDimension` when it is not just a plain 2D texture and the loader could/did not identify what it should be.
