Fix glsl DEFORM_BULGE calculation
Fix white flash levelshot bug in OpenGL1

If you tried to draw the last loaded image, gl texture 0 (which is appearently white)
was used because renderer thought the image was already bound.

Why OpenGL1 renderer binds texture 0, I have no idea. It's been removed from OpenGL2.
