AMD drivers reject system memory surfaces that are larger than the maximum texture width/height supported by the driver (usually 4096x4096 for AMD). This can cause issues in games that create larger system memory surfaces. This workaround crops the driver resource dimensions to the allowed maximum values and handles blitting outside this region by creating a temporary resource that maps to the actual affected system memory region. Fixes crashes with AMD drivers in Rainbow Six games and Desperados, mentioned in issue #2 and #8.
