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()
