cd1112f7ac allow percentage sizes
change height and width options to be floats, and interpret values
between 0 and 1 to be percentages.  For example, an options strings of
"0.5x" specifies 50% width and proportional height.

036d0c51c4 allow setting max height and width
This is primarily added to prevent a denial of service attack where
insanely large images are requested, eating up CPU.

8310f6eb79 properly handle thumbnail requests
if both height and width are specified, we assume you want an image at
exactly those dimensions, so use imaging.Thumbnail, which will resize
and crop the image.

if either height or width are left unspecified, then it's just a simple
resize request.

2794d47390 accept "fit" option
this also relaxes option parsing to never return an error.  In cases
where options are not able to be parsed, they are silently ignored.
