H. Verbeet daa59e00be wined3d: Call LoadLocation() on higher render targets as well, simplify some code in drawPrimitive. 
It's probably rare for higher render targets to get locked or updated
from sysmem, but this should still be more correct. It also makes the
code simpler.

* The problem is that OpenGL does not offer a direct way to return the tesselated primitives,

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