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.

The new version has many more features than the old one. This update
is necessary for an upcoming update to Icon-O-Matic adding perspective
transformers.
This update is pulled from https://github.com/ghaerr/agg-2.6 at commit
e7db22bd12700118257b4cb780539c421e01aa51 with our changes applied on
top. Note that this repository isn't necessarily the chosen upstream
that all future updates should be pulled from. See the discussion
starting at [1] for more information.
This also updates the affine transformation since the newer perspective
transformation requires the newer version.

I assume the intent was the same as in other similar functions above.

A lot of these classes are not *technically* "trivially copyable"
for one reason or another, but in all of these cases it seems
OK to me to use memcpy/memset on them. Adding a cast to void*
tells GCC that "I know what I'm doing here" and shuts up the
warning.
It was licensed with a "no commercial usage allowed" license, which if
we were using it would be a gray area at best. We weren't using it at all,
and AGG seems to have disabled building it by default, so just remove it
from the tree entirely.
Briefly discussed on IRC.
* Simplified the subpixel related methods for the AGG "pixel format" template
interface, the ones for the solid cover simply pass through the existing
methods, so only one subpixel blending function is left which does the actual
work (this removes a lot of the previously added code)
* Implemented a new rasterizer based on the original AGG rasterizer which
implements subpixel anti-aliasing for any generic AGG vector pipelines. It
is now optionally used in Painter and AGGTextRenderer (for vector fonts, ie
rotated, sheared or big enough fonts) depending on the global subpixel
setting.
* Put all subpixel variables into the new GlobalSubpixelSettings.h|cpp
* Simplified DesktopSettings related classes a bit and renamed previous
FontSubpixelAntialiasing to just SubpixelAntialiasing.
* The private libbe functions for subpixel related settings moved from Font.cpp
to InterfaceDefs.cpp where other such functions live. They are not related
to fonts only anymore.
* Removed the subpixel related settings again from the Fonts preflet and added
them to the Appearance preflet instead.
All of the above implements subpixel anti-aliasing on a global scale, which
to my knowledge no other OS is doing at the moment. Any vector rendering
can optionally use subpixel anti-aliasing in Haiku now. The bitmap cached fonts
are still affected by the Freetype complile time #define to enable the patented
subpixel rasterization (three times wide glyphs). Vector fonts and shapes are
not affected though at the moment.

* Prepared the AGG base_renderer code with two more functions needed to
handle subpixel scanline coverage values.

* removed the useless parts of AGG (which are only needed for the
interactive examples)
* make sure to jam -a libagg.a to solve any linking issues
