This is a complete removal of code that utilizes image_32 in the library. It is a sweeping change that does some of the following:

Browse source 
* Changes all agg_renderers to use a image_data_any variant (only image_data_rgba8 is implemented currently)
* Changes the marker and marker_cache to use image_data_any images
* Changes the symbolizers so that they must be aware of the source data type they are attempting to render and the render type that is expected to be rendered into.
* Moves many utilities into image_utils, that were previously in image_32.

The kicker is that this still isn't working perfectly yet, but I am commiting so I don't have tears in case everything is lost on my computer.
