* is specified by GrAA) is almost equivalent to kNone or kAll, with the exception of how MSAA is
* handled.
*
* When tiling and there is MSAA, mixed edge rectangles are processed with MSAA, so in order for the
* tiled edges to remain seamless, inner tiles with kNone must also be processed with MSAA. In
* regular drawing, however, kNone should disable MSAA (if it's supported) to match the expected
* appearance.
*
* Therefore, APIs that use per-edge AA flags also take a GrAA value so that they can differentiate
* between the regular and tiling use case behaviors. Tiling operations should always pass
* GrAA::kYes while regular options should pass GrAA based on the SkPaint's anti-alias state.
