The focus is on established linux graphics tools and formats and then using CPAN modules to interface them. Unfortunately many CPAN modules like GD::Graph is dead slow processing large data.

I'm missing more indepth information like how to write an effective graphic language state machine (aka openGL), build 3D graphic-objects, Direct rendering support, Shaders, direct access to the png-lib, tuning your graphic objects for max performance under perl etc. clearly outside the scope of the book.
