* bug#33990: 27.0.50; image-transform-fit-to-height/-width violates assert

When I resize images, using image-transform-fit-to-height or
image-transform-fit-to-width, the scaling is performed but than
image-transform-check-size is called and signals an error.  This uses
ImageMagick 6.9.7.4 as installed by Debian GNUS/Linux 9.6 (stretch).

Also, because the scale factor is kept globally after that operation (is
that intentional BTW?), loading other images afterwards also runs into
that error, thus image-mode fails to execute and instead in new image
buffers the raw bytes are shown.

I can reproduce this on emacs-26 as well as master with "emacs -Q" with
PBM and with JPEG images.
