This adds a checkbox to the debugger to allow seeing the effect pathops has on the clip. A new tab shows the C code that the pathops generate.
Once in place, this CL found a bug in the pathops code where it was not handling empty clip stack elements correctly. The Cl also has the change to SkCanvas to fix this bug.
