Introduce Icon Theme cache handling framework
Icon Theme cache files are used by GTK+ and maintained with the
gtk-update-icon-cache tool. Each Icon Theme package duplicates
its own maintainance scripts: only the specified icon theme directory
differs. With this framework, if packages have ICON_THEMES=yes,
associated icon themes will be detected and their cache files will
be maintained automatically.
Change cache handling behaviour as follows:
* Icon theme caches will be updated if either gtk2+ or gtk3+
gtk-update-icon-cache tool is available.
* With installation of gtk2+ package, not only hicolor icon theme but
also any other icon theme cache files will be updated.
* Prevent removal of icon caches at deinstall, gtk3+ may be installed and
using them.
* Ditto with gtk3+, gtk2+ may not be installed now, so caches must be
maintained by gtk3+.
by creating/deleting them from the (de)install scripts (and not registered
in the PLIST). This allows pkg_tarup to work properly and also avoids some
warnings during 'make replace'.
Changes since 2.4.2:
* GtkButton
- Give extra space to children of !CAN_FOCUS buttons [Matthias Clasen]
* GtkFileChooser
- Make DND work when the dialog is modal [Federico Mena Quintero]
* GtkToolbar
- Don't show empty overflow menu [Soeren Sandmann]
- Don't show initial separator in overflow menu [Soeren]
- Handle dynamic changes to overflow menu [Soeren]
* Documentation improvements [Bastien Nocera, Matthias]
* Other bug fixes [Matthias, Soeren, Sven Neumann]
* Updated translations (hu,ne)
files are not intended to be configured by the end user, but should be
automatically regenerated when (de)installing extra GTK modules.
Bump PKGREVISION to 3 because of this change.
While doing this, implement a framework so that other packages installing
GTK modules can rebuild those databases easily at (de)install time.
