November meeting: The Seattle-area face-to-face meeting date is not yet set
in stone yet but will very likely be on Nov 21-22. I hope to nail that down
in the coming two weeks. We will try to include telecon access for those who
cannot attend in person.

Scope and goals: Note that the statement of goals was refined a bit at
Saturday's meeting -- it's still basically the same direction as originally
posted but with some refinements such as excluding things like buttons and
similar UI elements. The consensus of the group so far is to stick with a
"lite" bounded portable subset for the first version.

We could name the first targeted TS as "2D Lite" (note emphasis on "lite" --
this is not intended to compete with a full-fledged professional graphics
library):

    (a) immediate mode graphics/text canvas, plus

    (b) basic keyboard/mouse style input.

That's a pretty portable subset that's already widely supported by many C
and C++ libraries.

We want to be example-driven, and so far people have proposed three specific
examples we'd like to see a proposal demonstrate can be written easily and
clearly (more examples are welcome):

1. The "Hello world" challenge: Drawing the text "hello world" and dragging
it around the canvas. The code should be only slightly longer than a console
"hello world" program.

2. The "sort visualizer" challenge: Visualizing a sort algorithm by drawing
a bar with length proportional to each element at each stage. This ought to
take <20 lines of code (not counting the sort algorithms themselves).

3. The "four-hour" challenge: Some who has never seen the library should be
able to build something interesting from scratch in four hours or less. (We
have multiple existence proofs including Cinder, OFX, and SFML; see these
two 10-minute videos: http://tinyurl.com/m5kd7h4 and
