Clean up unneeded code in agg and skia driver
- The agg driver never initializes an ICC transform and always uses an alpha_flag equal to 0 in a couple of methods. - The skia driver is not using CFX_Renderer. If it needs it later, we should move it out of fx_agg_driver.cpp into its own file, instead of duplicating the code.
