Glyphs represent a set of pixels for a 2 dimensional region of a
plane.
x, y: The minimum x and y coord of the region in pixels.
w, h: The width and height of the region in pixels.
samples: The sample data. The sample data is in a compressed format
designed to give reasonable compression, and to be fast to plot from.
The first sizeof(int) * h bytes of the table, when interpreted as
ints gives the offset within the data block of that lines data. An
offset of 0 indicates that that line is completely blank.
The data for individual lines is a sequence of bytes:
00000000 = end of lines data
LLLLLL00 = extend the length given in the next run by the 6 L bits
given here.
LLLLLL01 = A run of length L+1 transparent pixels.
LLLLLE10 = A run of length L+1 solid pixels. If E then this is the
last run on this line.
LLLLLE11 = A run of length L+1 intermediate pixels followed by L+1
bytes of literal pixel data. If E then this is the last run
on this line.
