I think the core support is ready now, but I'd like feedback on the color key ioctl. It would be good to have a way to disable it at runtime (w/o color keying enabled, the sprite will always sit on top of the primary), and potentially add alpha support at some point. Would 0 as the color key work well enough as a "disable" flag? Or should I add a separate field to the ioctl? Anyone have a preference? Thanks, Jesse
