[SciPy-dev] Patch for broken scipy.plt.plot_objects.py

[A.Schmolck]

Hi,

I didn't find anything specific on the www.scipy.org on how to submit patches,
so I hope submitting them here is OK.

I hit upon a bug in plt.imagesc, that took me quite a long time to track
down. Basically, it won't display any non-square matrices correctly. However,
reshaping a flat array (which I happen to mostly work with), incorrectly
(i.e. reshape(a.flat,(col, row)) instead of reshape(a.flat, (row, col))), will
result in the plot one expected. I was therefore quite dumbfounded when I
found that plt.imagesc(reshape(a.flat,(col, row))) worked but
plt.imagesc(transpose(reshape(a.flat,(col,row)))) produced garbage.

Here is a fix (plus anoter small change), which I hope should work.
