tim doerries 19f9cbffa0 Implemented support for SparseVolumeTextures falling back to coarser mip levels at page level. This is the first step in moving towards streaming at page granularity instead of mip level granularity. The main problem to solve here is to update the descendands of every streamed in/out page so they point to the proper fallback mip data. In this CL, this is done on the CPU using a new always loaded octree representing the sparse page table topology as well as bitsets to keep track of changes in page GPU residency. In the future, we could maybe move this step to the GPU: For every valid mip0 page a CS thread would walk up the mip chain to find the finest resident mip level to fall back to and then write it to all the relevant pages along the path to the parent. ...
