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 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.

Removed the background and set/get background from image_32 class. Removed clear method from image_32. Added new fill method for image_data_any, that allows many generic types to fill an image.

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.

Updates for Ref #2594 and #2592 (Related to #2491 )
...
* Added support for scanline, stripped and tiled
* Added new configuration options for TIFF:
- method
- tile_height (Default 0)
- tile_width (Default 0)
- rows_per_strip (Default 0)
* Removed 'scanline' configuration option for TIFF.
* Changed RGBA TIFFs to be ASSOCALPHA rather then UNASSOCALPHA

Series of changes for the tiff encoder:
...
* Added configuration options for the TIFF encoder. The options are:
- compression: adobe_deflate(default), deflate, lzw, none
- zlevel: 0-9
- scanline: 1,0 (Forces scanline encoding)
* Fixed bug in encoder with scanline where memory was being modified
* by TIFFWriteScanline. A buffer is now created for each row to prevent
* modification of the underlying image_data.

Fixed error with selection criteria for stripe vs tiled, added modulus check on length and width to select striped in some situations, changed bitspersample for RBGA. (ref #2491 )

Updated tiff processing so now the encoder will utilize different types of data as well as will use Tile based encoding in most situations, if the image is large will revert to scanline based encoding.
