Simple, clean theme engine...

./configure [--prefix=/where/you/want/it]
make
make install

Then either use the Gnome Control Center to select the theme or put the
following into your ~/.gtkrc :

include "$prefix/share/themes/ThinIce/gtk/gtkrc"
($prefix is what you sent to told configure, or /usr/local if you said nothing)

You can apply different engine styles to different widget (or widget classes).
The scrollbar uses mark_type1 for the slider and mark_type2 for the buttons
on the end. Handles on toolbars uses mark_type1.
Valid options for the mark types are:
NOTHING - nothing
SLASH - single (buttons) or double (slider + handles) slashes
INVSLASH - inverted slash(es)
DOT - dot(s)
INVDOT - inverted dot(s)

The styles 'handlebox_marks', 'scrollbar_marks' and 'scroll_button_marks' are
kinda deprecated.. almost.. they're just mapped to the mark_typeX styles..

Enjoy!
