- The initial wipe screen is now kept in video memory. I had previously
assumed that since the wipes only run at 35 FPS, the time spent DMA'ing
it from system to video memory would be acceptable. Apparently I was wrong.
In particular, updating the same surface several times probably has to
synchronize between each one, making melt particularly slower than it
needs to be.
November 29, 2009 (Changes by Graf Zahl)
- fixed: Line_SetBlocking and Line_SetTextureScale were not in the list
of action specials used by DECORATE or MAPINFO.
