//Clip establishes a new clip region by intersecting the current clip region
//with the current path as it would be filled by Fill and according to the
//current fill rule.
//
//After Clip, the current path will be cleared from the cairo context.
//
//The current clip region affects all drawing operations by effectively masking
//out any changes to the surface that are outside the current clip region.
//
//Clip can only make the clip region smaller, never larger.
//But the current clip is part of the graphics state, so a temporary restriction
//of the clip region can be achieved by calling Clip within a Save/Restore pair.
//The only other means of increasing the size of the clip region is ResetClip.
//
//Originally cairo_clip.
