public class RotatableQuadsTextureRenderer
extends java.lang.Object

Author:

Pierre Lando, Manuel Juliachs Performs the rendering of a rotatable 2D sprite using textured quads. To do: -implement correct screen-space aligning relative to the anchor point, as its apparent position may vary when changing the dimensions of the texture and/or rendered image, or its coordinates (possibly caused by subpixel accuracy and other related rasterization issues). -refactoring (e.g. draw's initialization calls).
