Removed ctx->Driver.LogicOp().

Browse Source 
ctx->Driver.Index/ColorMask() now return void.
Removed SWmasking and SWLogicOpEnabled variables.
LogicOps and color/index masking are no longer special-case device
driver functions.  The Xlib driver was the only driver that used
them.  Things are more uniform now.
