SCUMM: FM-TOWNS: Add optional trimming to 200 pixels height #2913
Trimming the screen to 200 pixels allows using aspect ratio correction.
Aspect ratio correction for FM-TOWNS has been requested for long time.
I have written this code 1 year ago, and waited for appropriate testing for Loom, as it's the most problematic game to trim, since it's really using the extra 40 pixels. The time has passed, and I decided to send this PR, without Loom.
The other games besides Loom are much safer - Zak uses the extra space for inventory, and it's handled in this PR. The other games don't use it at well.
