Given the compute based texture read path may be used for this, if format conversion is required, this flag should also imply general texture read support. This resolves a bug with GreasePencil fill which relies on this. Authored by Apple: Michael Parkin-White Pull Request: https://projects.blender.org/blender/blender/pulls/108463
