Can you move "64 * 1024 * 1024" to a constant defined with other constants in
anonymous namespace and add a comment next to it explaining what it's for? I'm
thinking something along the lines:

"Maximum allocation size allowed for image scaling filters that require
pre-scaling. Skia will fallback to a filter that doesn't require pre-scaling if
the default filter would require an allocation that exceeds this limit."

nit: move this call up next to the other SkGraphics call to keep these scaled
image cache related adjustments grouped together

Done.

Done.
