// The interesting part here is how to calculate bounds for ops which don't
// have intrinsic bounds. What is the bounds of a Save or a Translate?
//
// We answer this by thinking about a particular definition of bounds: if I
// don't execute this op, pixels in this rectangle might draw incorrectly. So
// the bounds of a Save, a Translate, a Restore, etc. are the union of the
// bounds of Draw* ops that they might have an effect on. For any given
// Save/Restore block, the bounds of the Save, the Restore, and any other
// non-drawing ("control") ops inside are exactly the union of the bounds of
// the drawing ops inside that block.
//
// To implement this, we keep a stack of active Save blocks. As we consume ops
// inside the Save/Restore block, drawing ops are unioned with the bounds of
// the block, and control ops are stashed away for later. When we finish the
// block with a Restore, our bounds are complete, and we go back and fill them
// in for all the control ops we stashed away.
