Revert "Remove SkDraw from device-draw methods, and enable device-centric clipping."

This reverts commit c77e33f73d3e86cfabf925d6f2e1166f81022575.

Reason for revert: breaks isClipRect
- this CL inspected the conservative clip for this, which is (by definition) a rect
- probably need to query the device for this info
