- rename standard integer types to a more familiar (u)int(8/16/32) - many function/struct renames. i don't _really_ know if what i've done for this is better, but it "feels" better to me. many draw/blit function names are shorter which is nice, at least. kinda important to me because i develop this on a real DOS machine in 80x50 text mode. - add 'extern "C"' blocks to headers for C++ compiler usage - draw/pixel color value arguments for functions should all have been changed to be uint8 instead of a full 32-bit int. feels right, but maybe should've left alone... - small fix to keyboard handler. noticed a problem on one thinkpad laptop. was a result of what i think was a typo in a constant value used during the part of the interrupt handler that tells the keyboard controller the key event was processed - fix uncommon potential crash function return in draw_filled_rect - renamed low-level "direct" assembly functions to "lowlevel_xxx" to be a little bit more explicit about what they are - add some convenience event helper functions for determining event types - add fixed point atan2 - fixed some tabs/spaces inconsistences (should all be spaces now?) - maybe some other minor things i've forgotten
