Reland "Fix precision caps and rrect/ellipse effect precisions"

This is a reland of e42180022720f2fcfd3c634cad855506a7940591
Original change's description:
> Fix precision caps and rrect/ellipse effect precisions
>
> Replaces all the complex precision caps with a single flag that says
> whether "float" == fp32. Updates the ellipse and rrect effects to
> use float coords, and use the scale workaround when float != fp32.
