What does texture resolve mean?
I don't know about other contexts, but for DirectX resolving a texture means blending multi-sampled texture into a non-multisampled one. For simple scenarios this is usually done automatically by the output merger, but is often needed to be done explicitly (e.g. ResolveSubresource) when using multi-sampled render target as an input for a next render pass (e.g. post-processing). Reasons being both performance and lower complexity of the following pass shaders.
