Updated AAClips Sample slide to demonstrate clipPath/clipRect methods

I've been using this sample to bootstrap the various clipping implementations and thought it might be time to check it in.

In addition to adding the clipPath/clipRect path this delivery also extends the slide to demonstrate more of the boolean ops (i.e., reverse diff & replace)

Can you apply the changes to gm/complexclip2.cpp instead? It might require
rebaselining but we'll have ongoing testing. (This and many of the Sample/GMs
predate the ability to view GMs inside SampleApp and so were duplicated). We
should delete this file and other Samples that are now redundant.

I have updated complexclip2 to test antialiased clipping on both paths and
rects.

I would like to keep the AAClips SampleApp slide for a while since it does
provide simple boolean cases vs. the 5-level randomized booleans of
complexclip2. What do you think about making AAClips into a GM (e.g.,
simpleclips) (in a separate CL)?

LGTM. Sorry, I conflated SampleAAClip2 and complexclip2 earlier.
