skia2/samplecode/SampleApp.cpp
csmartdalton 008b9d80ab Add the ability to enable/disable GPU path renderers 
Adds a bitfield to GrContextOptions that masks out path renderers.
Adds commandline flags support to set this bitfield in tools apps.
Removes GrGLInterfaceRemoveNVPR since we can now accomplish the same
thing in the context options.
