Subject: Doesn't reset the stream pos to 0 in CanRead().
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/a05da1b6827f40c0beb97225e9861356343e196b

Doesn't reset the stream pos to 0 in CanRead().

Please note that the PCX handler still cannot read images
embedded in streams because it has to check for some things
at the END of the file before proceeding!
