7ba3f124eb cleanup license headers and contributing docs 
- switch to "project authors" style copyright.  Instead of an AUTHORS
  file (https://opensource.google/docs/releasing/authors/), I just list
  Google as a major copyright holder in the README.
- use SPDX style license headers in source files
- remove CLA requirement from contributing docs

d4ba5205ff 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.

67619a67ae 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.

4533f0c68a 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.

328044540e add webp support (decode only) 
if any transformation is requested, webp images will be encoded and
served as jpeg or png, defaulting to jpeg if no format is specified.

b9cc9df4b6 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.
