Make the GM tool run GMs through an SkGPipe.

Make the GM tool run GMs through an SkGPipe.

Add pipe to core gyp project.

Do not run samplerstress through the pipe, since its
custom MaskFilter will not draw correctly.

Fix an assert in SkGPipeWrite when writing a typeface.

This change is not necessary for this CL. Will remove.

maybe its time to just roll the pipe code into gyp/core

Just need to call writePad()

In my next CL, I have added the pipe files to core, removed pipe.gyp, and
responded to the other comments.
