Use const path in SkPathContainsPoint

Treat received Path as a const.

Skia internally will either create a new Path object in a call
to 'transform' or can do it inplace if the destination pointer
is the same as the source.

By copying the Path object on start, we can treat the received
Path as a const reference instead of a pointer and save 2 function
calls to set/restore the fill type.

LGTM

Please update the patch title to be a little more descriptive. Maybe "Use const
path in SkPathContainsPoint"?

https://codereview.chromium.org/19846006/diff/1/Source/core/platform/graphics...
File Source/core/platform/graphics/skia/SkiaUtils.cpp (right):

https://codereview.chromium.org/19846006/diff/1/Source/core/platform/graphics...
Source/core/platform/graphics/skia/SkiaUtils.cpp:174: scaledPath.transform(m,
0);
Oh my, we create a transform just to scale the path? I bet there's another nice
speedup if we just add void path::scale(float, float)!

Just pointing this out in case you want to play in this space in a future patch
:)
