add support for bmp images
...
handle decoding and encoding bmp images with transformations. Because
this isn't a popular file format, we don't actually expose it as an
option for format transformation.

add support for exif orientation tag

if any transformation is requested, first apply any additional
transformation necessary to correct for the EXIF orientation tag, since
it is stripped from the resulting image.

allow crop options to be floats and negative
...
values between 0 and 1 have the same behavior as the size option - it is
treated as a percentage of the original image size. Negative values for
cx and cy are calculated from the bottom and right edges of the image.

add support for specifying output image format
...
For now, the options are "jpeg" and "png". Gif is a little harder to
support because of the way we use the image/gif package to handle
animated gifs. I have also have trouble imagining someone wanting to use
gif over png. But if the need really exists, we can address it when it
comes up.
