gsdx: hidden option disable_hw_gl_draw 

OMG, Zone of Ender got a speed boost from 11 fps to 45 fps

Seriously, the goal is to allow benchmarking GSdx without too much overhead of the main renderer draw call

Note: unlike the null renderer, texture/vertex uploading, 2D draw, texture conversions are still done.
