747 * and they can't be sent off for rendering directly either. Tesselating is slow, so we want
748 * to cache the patches in a vertex buffer. But more importantly, gl can't bind generated
749 * attributes to numbered shader attributes, so we have to store them and rebind them as needed
752 * To read back, the opengl feedback mode is used. This creates a problem because we want
753 * untransformed, unlit vertices, but feedback runs everything through transform and lighting.
754 * Thus disable lighting and set identity matrices to get unmodified colors and positions.
755 * To overcome clipping find the biggest x, y and z values of the vertices in the patch and scale
756 * them to [-1.0;+1.0] and set the viewport up to scale them back.
758 * Normals are more tricky: Draw white vertices with 3 directional lights, and calculate the
759 * resulting colors back to the normals.
761 * NOTE: This function activates a context for blitting, modifies matrices & viewport, but
762 * does not restore it because normally a draw follows immediately afterwards. The caller is
763 * responsible of taking care that either the gl states are restored, or the context activated
764 * for drawing to reset the lastWasBlit flag.
