jmatthewgriffis/ofxSpriteSheetRenderer
My fork of Zach Gage and Ramsey Nasser's ofxSpriteSheetRenderer adds support for 1) sprite sheets that are not width/height-equal (i.e. square) and do not have to be a pow2 size, and 2) animation sequences that span multiple rows on the sheet (the latter functionality was later pulled into the source). The "not-square" branch includes both changes.
