Detailed Description

Font description struct.

The TFont contains a description of the font, including pointers to the glyph data and width data (for VWF fonts), an ascii-offset for when the first glyph isn't for ascii-null (which is likely. Usually it starts at ' ' (32)).
The font-bitmap is a stack of cells, each containing one glyph each. The cells and characters need not be the same size, but the character glyph must fit within the cell.

The formatting of the glyphs themselves should fit the rendering procedure. The default renderers use 1bpp 8x8 tiled graphics, where for multi-tiled cells the tiles are in a vertical 'strip' format. In an 16x16 cell, the 4 tiles would be arranged as:

0 2
1 3
