* Initial test for texture sync * WIP new texture flushing setup * Improve rules for incompatible overlaps Fixes a lot of issues with Unreal Engine games. Still a few minor issues (some caused by dma fast path?) Needs docs and cleanup. * Cleanup, improvements Improve rules for fast DMA * Small tweak to group together flushes of overlapping handles. * Fixes, flush overlapping texture data for ASTC and BC4/5 compressed textures. Fixes the new Life is Strange game. * Flush overlaps before init data, fix 3d texture size/overlap stuff * Fix 3D Textures, faster single layer flush Note: nosy people can no longer merge this with Vulkan. (unless they are nosy enough to implement the new backend methods) * Remove unused method * Minor cleanup * More cleanup * Use the More Fun and Hopefully No Driver Bugs method for getting compressed tex too This one's for metro * Address feedback, ASTC+ETC to FormatClass * Change offset to use Span slice rather than IntPtr Add * Fix this too
