Minor tweaks to README
Calculate final sizes, and resized_img_attrs(..., dpi_scale=2) for "retina" displays
Don't stick `None` values into the URL
Be able to deal with enlargements; kinda gross
Another misguided attempt at enlargements before rebuilding
Properly deal with enlargements, test size calculations; drop dpi_scale (for now)
Basic retina support
Pass retina scale to HTML as data-retina
Properly set retina_quality
resized_img_tag, and small fixes
s/retina/hidpi/ and s/Size/ImageSize
PyPy on Travis does not seems to like Flasks ext import magic all that much
First stage of unsharp-mask filtering
Any kwarg can be hidpi_*
Bump to v2.1.0
