A corrupt or malicious font may have a negative size in its cmap
range, which in turn could lead to memory corruption. This patch
detects the case and rejects the font, and also includes an assertion
in the sparse bit set implementation if we missed any such case.

Replaced two instances of negating an unsigned long, which was
resulting in aborts from unsigned integer sanitization with the
equivalent logical not-add 1.

This is the initial draft of Minikin, a library intended to perform text
layout functions. This version does basic weight selection and font runs
for scripts, and also has a simple renderer for drawing into bitmaps,
but is lacking measurement, line breaking, and a number of other
important features. It also lacks caching and other performance
