* X-GLCD Font format:

* First byte of glyph is it's width in pixels.
* Each data byte represents 8 pixels going down from top to bottom.
*
* Example glyph layout for a 16x16 font
* 'a': [Glyph width][Pixel column 0][Pixel column 1] where the number of pixel columns is the font height divided by 8
* 'b': [Glyph width][Pixel column 0][Pixel column 1]...
* 'c': And so on...
