The transient-attachments feature allows creation of attachments that allow render pass operations to stay in tile memory, avoiding VRAM traffic and potentially avoiding VRAM allocation for the textures.
Example Usage:
wgpu::TextureDescriptor desc;
desc.format = wgpu::TextureFormat::RGBA8Unorm;
desc.size = {1, 1, 1};
desc.usage = wgpu::TextureUsage::RenderAttachment | wgpu::TextureUsage::TransientAttachment;
auto transientTexture = device.CreateTexture(&desc);
// Can now create views from the texture to serve as transient attachments, e.g.
// as color attachments in a render pipeline.
