Subject: [PATCH 038/197] After the fix still causing issues, I figured the
 value must be >0xffff_ffff so not fitting. I changed to logic to handle that
 case too.

Subject: [PATCH 182/197] Changed SKPaintCache.Return to ReturnReset. Added
 SKPaintCache.Return which only returns the paint and does not reset. Removed
 PaintWrapper._disposePaint. Removed all method call's references to setting
 PaintWrapper._disposePaint.
