1192 * to chache the patches in a vertex buffer. But more importantly, gl can't bind generated

1194 * in drawprim.
1195 *
1196 * To read back, the opengl feedback mode is used. This creates a proplem because we want
1197 * untransformed, unlit vertices, but feedback runs everything through transform and lighting.
1198 * Thus disable lighting and set identity matrices to get unmodified colors and positions.
1199 * To overcome clipping find the biggest x, y and z values of the vertices in the patch and scale
1200 * them to [-1.0;+1.0] and set the viewport up to scale them back.
1201 *
1202 * Normals are more tricky: Draw white vertices with 3 directional lights, and calculate the
1203 * resulting colors back to the normals.
1204 *
1205 * NOTE: This function activates a context for blitting, modifies matrices & viewport, but
1206 * does not restore it because normally a draw follows immediately afterwards. The caller is
1207 * responsible of taking care that either the gl states are restored, or the context activated
1208 * for drawing to reset the lastWasBlit flag.
