ClearArea
---------
Basically a special case of PolyFillRect. Put up some sort of image first
so we can clear it away. Try both small areas and big areas, to give
credit to servers for optimizing small ones.
Data: Pixels per second.
Breaking that down into large and small areas would probably not
be userful.
GC Fields: None.
CopyArea
--------
Putting up some image and then repeatedly copying from one part of it
to another would do the right thing and could look neat if done right.
We probably want to see what happens when the source area is clipped,
as that as mentioned specifically in the protocol document.
Data: Pixels per second.

subwindow-mode

clip-x-origin

CopyPlane
---------
Special case of CopyArea again.
PolyPoint
---------
Draw lots of points.
Either start out with an image that's 50/50 black and white
(preferred) or draw enough points that some points will get drawn at
least twice (to test functions other than copy).
Data: Points per second.

PolyLine
--------
Circular test like there is now.
Try clipping at window boundaries?
Data: Lines per second.
Pixels per second (is this valid - do lines that are twice as
long take twice as long to draw? Also, is it valid to compare
thin lines and fat lines?)

PolySegment
-----------
Just like PolyLine but lines don't have to be connected. Crosshatching?
Data: Lines per second, pixels per second(?)

PolyRectangle
-------------
Lots of five point PolyLines. Partly concentric ones would look nice; we
also need overlap for testing different functions.
Data: Rectangles per second.
Pixels per second? (divide by perimeter)

PolyArc
-------
Overlapping concentric things (ripples) would look cool.
Is it possible to special-case circles? Test for this?
Data: Arcs per second? If we had the same test each time this might
be OK.
Pixels per second? Finding the length of an arc could be
annoying.

FillPoly
--------
Use the same test as PolyLine?
Overlapping is a must to test functions.
Convex vs. Concave polygons.
Data: Pixels per second, I guess.
Data for convex vs. concave could be interesting.

PolyFillRectangle
-----------------
Use same test as PolyRectangle?
Perhaps give FillPoly some of these too, see if it special cases them.
Fill Rectangle vs. Fill Poly for same size areas would be an
interesting comparison.
Data: Pixels per second.
