Known issues and limitations

-BC1 set to high-quality settings or with refinement steps take longer time to process than prior versions, adjust quality-settings lower if better performance is required
-Fixed quality issues for BC7 HLSL for images with alpha content, the processing time is longer than the previous release
-Global Setting of Refine Steps is only valid for BC1, it will not work for any other format settings.
