- [NEW] res() without arguments returns width and height of window.

- [NEW] camera() without arguments returns 'x' and 'y' of camera.
- [NEW] palcolor() to set or get a color from the palette (replaces setcolor() & getcolor() ).
- [NEW] paltrans() to set or get which color index is transparent (replaces settrans() & gettrans() ).
- [RENAME] sspr() to blit(), spr_r() to blit_r()
- [NEW] mouse() returns both x and y mouse coordinates.
- [DEPRECATED] setcolor(), getcolor(), settrans(), gettrans(), spr(), sspr(), spr_r(), mousex(), mousey(), abs(), ceil(), flr(), sgn(), sin(), cos(), atan2(), sqrt(), max(), mid(), min(), tostr(), ascii(), strlen(), fopen(), fopenres(), fclose(), feof(), fwritei(), fwrited(), fwrites(), fwritew(), fwriteb(), fwriteln(), freadi(), freadd(), freads(), freadw(), freadb()
- [FIX] Now the background on resizable windows  is filled with black instead of garbage.
- [FIX] Compiling on Linux uses POSIX functions.
