virtual/imagemagick-tools: Add virtual for media-gfx/{image,graphics}magick
* Packages that do **not** link to either library and just consume the
runtime command-line tools of either package should depend on the virtual
in general. This reduces the complexity of the depgraph and makes central
USE flag handling much easier.
* Packages that can link to either imagemagick or graphicsmagick need more
delicate handling in order to be usable with subslots.
1) Packages that **require** either imagemagick or graphicsmagick should
use USE="graphicsmagick" to differentiate which one to use by specifying
!graphicsmagick? ( media-gfx/imagemagick:= )
graphicsmagick? ( media-gfx/graphicsmagick:= )
2) Packages that **may** use either imagemagick or graphicsmagick, but don't
**require** it, should additionally add USE="imagemagick" and specify
imagemagick? (
!graphicsmagick? ( media-gfx/imagemagick:= )
graphicsmagick? ( media-gfx/graphicsmagick:= )
)
So that the semantics become:
USE="imagemagick" = "I want to build with optional imagemagick or graphicsmagick support"
USE="-imagemagick" = "I do NOT want optional support for imagemagick and/or graphicsmagick"
USE="-graphicsmagick" = "I want to build against media-gfx/imagemagick"
USE="graphicsmagick" = "I want to build against media-gfx/graphicsmagick"
This avoids package.use pollution due to setting REQUIRED_USE.
