   Texcoords
  Quick question, sorry if this sounds stupid.  If I am loading a texture that is not square (wider than it is tall), is the vertical dimension still 0.0f to 1.0f and the horizontal dimension still 0.0f to 1.0f as well (i'm using OpenGL)?Thanks, all   
  Yes, the texture coordinates are always from 0 to 1.   ;  Awesome, that keeps things nice and simple.
