Summary: pix_dump does not properly after an image has been resized

Initial Comment:
pix_dump does not dump the pixel data properly of a greyscale video feed that has been resized to 25x25 pixels:
1) The number of pixels returned is 624 instead of 625!
2) If the dumped data is fed back to a pix_set the resulting image is garbage

Note: I want to resize the video to such a low resolution to send the pixel data by serial to a Peggy 2.

Message:
[pix_dump] in greyscale mode currently needs the number of pixels be
dividible by 4.
so if you can live with a 24*24  or a 26*26 image, you will be on the save
side.

anyhow, the issue only skips the remaining pixels, so adding dummy-pixels
manually could help...

i committed a fix to svn/trunk with revision #3357
i committed a fix to svn/branches/0.92 with revision #3359
