I didn't finish my attempt to understand the whole code but the main job for this code is to update attributes buffer and uncompress 1bit to 2bit.The code seems to use another table for direct pointers to chars.
The scrolling code (#8824) is interesting too, especially for its usage of the stack as pointer tableto do multiples calls.
