Date: Wed, 5 Nov 2003 21:27:47 +0100 From: Thomas Jarosch <xxx> To: Ryan C. Gordon <xxx> Subject: MGA CRTC2 update Hi Ryan, attached is a small update for the DirectFB MGA CRTC2 support: - Video aspect ratio correct scaling (important for MAME) - Small bugfix in previous scaling code - Ability to control the TV picture overscan via the environment variable SDL_DIRECTFB_OVERSCAN. Sounds worth enough for applying it to SDL CVS ;-) Cheers, Thomas
