Remove SkDrawIter entirely
SkDrawIter goes away, as well as the DRAW_BEGIN, DRAW_END, and
FOR_EACH_TOP_DEVICE macros. A new macro TOP_DEVICE is added that
simplifies checking for a null device (which is currently only possible
if SkCanvas::init() was called with null). The intent is that this will
be replaced with just "this->getTopDevice()->" in the future.
The rest of the auto-layer magic that happened in DRAW_BEGIN is now
explicitly written out in the draw functions. Additionally, it has
been updated to check for an image filter. When there's no image
filter, it completely bypasses the construction of the AutoLayer object.
This extra check maybe isn't worth the code complexity, but some draw
methods had previously followed this pattern, so presumably stack
allocating the AutoLayer had some overhead in tight draw loops.
