RenderEngine API: add viewport draw utility functions to bind a GLSL fragment
shader for converting colors from linear to display space, based on the scene
color management settings.
if engine.support_display_space_shader(scene): # test graphics card support
engine.bind_display_space_shader(scene)
# draw pixels ..
engine.unbind_display_space_shader()
