Vector Arrows in Image Plots

Hi,

I am excited about the relatively new imshow and pcolor features in
matplotlib. I am using numarray to reduce/diagnose planetary atmospheres
simulations, which consist of temperature and velocity data on gridpoints
in longitude, latitude, and pressure.

In addition to contour plots, which is on the goals list for this project,
I would like a feature added that allows me to make velocity arrows
overlaying the pcolor or imshow images, as is common in meteorology maps.
Will such a feature be available in matplotlib, and if so, how soon?
Thanks for all the great work so far!

Cheers,
Curtis
