I have no particular opinion about which exact function does it, but it
_should_ be done `transparently' -- that is any place where a lisp value
is used to compute deeper information (for display or otherwise).
Two important functions for that are `valid_image_p' (called by all
sorts of image-manipulation functions), and `lookup_image' (called by
the display engine). Both of those call `lookup_image_type', and thus
my placing a call to image-type-validation there.
If I omitted an argument, obviously my change was flawed, but the
location seems reasonable.
