0.16.1 breaks consumers

[wthrowe]

0.16.0 publicly exported texture-0.4.0::ImageSize, while 0.16.1 publicly exports texture-0.5.0::ImageSize. These types are different (in that an impl of one does not satisfy a requirement for the other) and the change breaks piston2d-opengl_graphics:

Agh of course, I'll yank 0.16.1 and publish 0.17.0. Thanks for the heads up.
