Icon-O-Matic: Add perspective transformations

Browse Source 
As part of adding perspective transformations, agg_trans_perspective.h
was patched to fix a multiple definitions error. This change has been
submitted for review to the "upstream" repositories at [1], [2],
and [3].

Also includes various other improvements such as VertexSource being
split into its own file, code style improvements, and documentation
improvements.
