eclipse-themes using gtk3 + eclipse-themes is snarly slow

Hi jeeeyul,

I realised when I use eclipse with the gtk3 render engine and have your theme engine render the UI eclipse is getting really slow. It's basically impossible to properly work with eclipse in this combination. Each button press, for instance, takes a few seconds until it gets serviced. When I switch to the default (gtk) eclipse theme things are getting better performancewise - not perfect though. Of course, eclipse then looks plain ugly. My resolution right now is to use the old gtk2 render engine.

how did you switch the gtk version? My eclipse has also slowed down considerably since installing the theme.

you have to set the environment variable SWT_GTK3=0

I can confirm this issue on [X]Ubuntu 16.04 (LTS) with both Eclipse 4.5.2 and 4.6, using XFCE 4.12, tested with Greybird and default XFCE Theme. Jeeeyul-ET is latest from update-site at the time of this writing...

Additional Info:

Tested Eclipse running both with (default) GTK3 Theme-Engine and old GTK2 using --launcher.GTK_version 2

As soon as I enable Jeeeyul-Eclipse-Theme under General -> Appearance -> Theme the 'slowness' starts, most noticeable when resizing a view (like explorer, outline, etc).

Switching back to Theme Classic or GTK3/GTK2 all runs smooth again, restarting eclipse after switching to Jeeeyul-ET does not resolve this either.

Switching to different Presets with Jeeeyul-ET enabled also has no effect on performance.
