- default drawing element is a tile, drawing functions will be passed
- parameters in terms of number of tiles instead of number of pixels.
- For example, to draw a single character, instead of using bitmaps,
- an index to an array of bitmaps will be used. To clear or move a
- rectangular section of a screen, the rectangle will be described in
- terms of number of tiles in the x- and y-axis.
