- Unified the screen buffers that are used by the current and the new GUI
- Replaced the FreeSCI line drawing code (which is actually Bresenham) with Graphics::drawLine(), after discussing with waltervn. This shouldn't bring any regressions, as we're no longer offering the option to scale the background at a vector level. After playing through some of the games, I haven't noticed any regressions
- Some cleanup
