* 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. Ref #2633
