Convert parts of elementary-xfce to png during pkg-build

[Simon Steinbeiß]

While it eases maintenance, svgs are partly causing problematic behavior in Xfce. The two most prominent examples are the panel and its plugins and xfwm4-tabwin (aka alt-tab). In either svgs result in ugly scaling, converting the icons in question to png completely fixes that.

Converting the whole icon-theme wouldn't make sense, especially icons in */symbolic have to remain svg to remain functional.
I'm proposing to convert at least the icons in apps/ and panel/
At the moment we're shipping the most crucial icons as svg and png, so another benefit would be that we could drop those duplicates.

Finally svgs are reportedly a bit slower than png in rendering with gtk, while I'm not an expert as to how much the difference really is it might be another argument to take into account.

I experimented a bit yesterday, and a partial conversion is a pain to handle at build time because of symlinks (panel/ is fine, apps/ is a nightmare), e.g.:

./elementary-xfce/stock/48/stock_new-meeting.svg -> ../../apps/48/system-users.svg
./elementary-xfce/stock/48/stock_people.svg -> ../../apps/48/system-users.svg
./elementary-xfce/actions/48/calibrate.svg -> ../../apps/48/gnome-display-properties.svg
./elementary-xfce/actions/48/system-upgrade.svg -> ../../apps/48/system-upgrade.svg
./elementary-xfce/emblems/48/emblem-people.svg -> ../../apps/48/system-users.svg
./elementary-xfce/emblems/48/emblem-shared.svg -> ../../apps/48/gnome-session-switch.svg
./elementary-xfce/emblems/48/emblem-urgent.svg -> ../../apps/48/clock.svg
./elementary-xfce/mimes/64/application-install.svg -> ../../apps/64/system-software-install.svg
./elementary-xfce/mimes/64/application-x-executable.svg -> ../../apps/64/application-default-icon.svg
./elementary-xfce/status/64/aptdaemon-download.svg -> ../../apps/64/system-software-install.svg
./elementary-xfce/status/64/aptdaemon-working.svg -> ../../apps/64/system-software-install.svg
./elementary-xfce/categories/48/applications-webbrowsers.svg -> ../../apps/48/web-browser.svg
./elementary-xfce/categories/48/preferences-desktop.svg -> ../../apps/48/gnome-desktop-config.svg

(these are examples, there are more of them actually)

These symlinks will be broken when I convert apps/ to PNGs.

[Simon Steinbeiß (ochosi)]

OK, I guess in this case we should convert everything _but_ the icons in symbolic. Usually there shouldn't be any symlinks (at least it wouldn't make any sense and I'd consider it a bug), so these directories are pretty isolated.

Would that make things easier?
