Karol Szwed 09141d02c3 Adding titlebar button autoshow/autohide when the title width 
increases/decreases. This makes small apps like the GIMP look much better,
and allows small windows to be shrunk much smaller than previously
allowed.

/*
Gallium-IceWM themeable KWin client
Copyright 2001
Karol Szwed (gallium) <karlmail@usa.net>
http://gallium.n3.net/
This client loads most icewm 1.0.X pixmap themes, without taking into account
specific font settings for clients, or coloured mouse cursors. Titlebar
fonts can be changed via the kde control center. Bi-colour mouse cursors
may be added in future if requested by users, as well as theme font support.
Any styles using inbuilt icewm titlebar drawing without using pixmaps (e.g.
Warp4, win95 etc.) are not fully supported, and may cause drawing errors,
as these themes use in-built icewm drawing mechanisms.
When a pixmap theme is not present (or a corrupt one is present) then very
plain title decorations are painted instead, so that users don't see
non-painted window areas where possible ;)
At a later date, frame shaping may be added if really requested, and an
update to support the latest icewm 1.1.X theme format may be made.
