[gentoo-dev] media-gfx/imagemagick vs. media-gfx/graphicsmagick[imagemagick] issue

[Pacho Ramos]

Hello

This is an old issue, how to allow the usage of either imagemagick or
graphicsmagick[imagemagick]:
https://bugs.gentoo.org/show_bug.cgi?id=314431

But most of the packages are not handling them at all, and some are
relying on || ( ) constructs... that then prevent us from relying on
subslots. 

Since we *need* that subslots for this case, I think we should handle
this in the way we handle ffmpeg vs libav: having a "graphicsmagick"
USE flag to pull in graphicsmagick when needed.

Is that ok? What other alternative would allow us to use subslots? :/

Thanks a lot
