We are unclear on the interaction design and we miss a visual design here...

My thoughts from an email:

I see in-chat sketching like a way to mix quick scribbles with the text, for
example to draw an equation or to highlight some text.
For real drawing we would need the full screen space and also we wouldn't want
this to be limited to the chat (hence it should be implemented like a stand
alone activity)

Anyway, for chat sketching, this to me implies that we really need to allow to
mix text and drawings in the same entry.

Bryan, what do you think?
