I agree, AGG (Anti-Grain Geometry) is an excellent model to 
follow, specifically for D. I've been using it in embedded 
systems running at 168MHz with less than 4MB of RAM.  And that 
RAM is also running a lot of other stuff (libPNG, FreeType, 
Modbus, and even embedded TrueType fonts.  Crazy!  I was actually 
shocked when I got it working, and saw it perform so well.

"AGG allows you to replace any part of the library, if, for 
example, it doesn't fit performance requirements. Or you can add 
another color space if needed. All of it is possible because of 
extensive using of C++ template mechanism.

Anti-Grain Geometry is not a solid graphic library and it's not 
very easy to use. I consider AGG as a “tool to create other 
tools”. It means that there's no “Graphics” object or something 
like that, instead, AGG consists of a number of loosely coupled 
algorithms that can be used together or separately. All of them 
have well defined interfaces and absolute minimum of implicit or 
explicit dependencies."

It's architecture is what makes it so beautiful.  You can 
configure your own graphics pipeline simply by passing the right 
template arguments.  It would be an excellent showcase for D.
