 {{{
 #!CommitTicketReference repository="" revision="37245"
 Media: Resolve fatal error on resize with ImageMagick < 6.4.6

 Improper checking for 'Imagick::ALPHACHANNEL_UNDEFINED' and
 'Imagick::ALPHACHANNEL_OPAQUE' caused fatal errors for some users
 with Imagick when compiled against ImageMagick < 6.4.6, when these
 constants were introduced. Fixes these compatibility checks.

 Merge of [37192] to the 4.5 branch.

 Props gblsm.
 Fixes #36501.
