Patch by David Reveman <reveman@chromium.org> on 2012-02-07
Reviewed by James Robinson.

PlatformCanvas constructor on win32 expects forth argument to be a
shared section handle. Passing a pointer to a system memory causes
it to crash. Fix this by not using the PlatformCanvas API for
SkCanvas construction in per-tile texture uploader.

Tested with manual tests.
