Bug summary

Currently, when X/Y are passed to pcolorfast and are regularly spaced arrays, pcolorfast just uses their first and last values for the image extents, without verifying that the coordinate sizes are actually correct.

Code for reproduction

from pylab import *
gca().pcolorfast(arange(5), arange(13), np.random.rand(20, 20))  # or whatever sizes

Actual outcome

no error

Expected outcome

a validation error
