SF: Reduce size of DisplayFrame according to "transparent region"

Calculating SourceCrop according to "transparent region" is taken care but
not DisplayFrame. DisplayFrame also need to be calculated according to
"transparent region" to avoid mismatch in SourceCrop and DisplayFrame.
This will avoid unwanted Scaling introduced because of mismatch.
