Added new image_cast method and added its bindings to python, added two new properities to images: offset and scaling. Added way to cast between image types with offset and scaling. Added new unit tests for color and casting. Made it so that pixel setting doesn't result in overflows or underflows. Made the return of get_pixel, dynamic based on what is passed to it. Added new methods for setting pixels that are doubles and ints.

Fixed some issues in color and bindings where you could create a color and premultiplied was not set and it was resulting in it being assigned randomly, causing some issues at runtime.
...
Updated some images in visual tests that were orginally set prior to all tiffs being premultiplied, this was causing a slight difference in a few pixels.
Updated the tiff tests a lot.
Fixed tiff reader so that it always considers everything read from RGB or RGBA as premultiplied. This is due to the fact that RGBA reader always premultiplies the alpha no matter its original form.
Put in a fix so that the file does not exist no longer shows up in the test running.
Fixed some failing tests in the c++ test due to tiffs now always being premultiplied for RGB(A)

Fixed the issues associated with TIFFs, now they always will return as premultiplied in the event they are rgba8 due to the way that the TIFF reader operates. Also added premultiply as a flag inside color class and exposed many of its components, made it so that setting and getting pixels took into consideration the state of the color and the image when dealing with the two.

Move image_data.hpp to image.hpp and renamed most everything from image_data to image alone. This might lead to the need to clean up some variables that are currently named image through out the code at some time, but I think in the long term is much better as image is a better name for the base class.

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:
...
* 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.

Moved set_alpha to src/image_util.cpp and out of image_32. Added a boolean response to premultiply_alpha and demultiply_alpha so that if it is changed in set_alpha and other locations like the python bindings for composite that the image can be restored to its original state. Removed blend from python bindings.

Added a lot of premultiply_alpha functions to attempt to have proper premultiplication of data prior to compositing. There still seem to be some errors in the resulting images, but I am not quite sure what they are yet.

Moved premultiply and demultiply out of image_32 and other parts of the code. The image_data object is now responsible for keeping track of its own premultiplied_alpha status. Created a new utility method in image_util to preform premultiplication.
...
Added visitor pattern to several different methods as well to prepare for image_data_any including compositing.
