gnome-panel transparency problems

[Kurt Fitzner <kfitzner excelcia org>]

I've been modifying the gnome-applets applets to work with 
pseudo-transparency now that it is working in gnome-panel, but have 
noticed what may be a bug.  Specifically, it is in gnome-panel's 
change-background signal.

When, in a panel's properties, the user changes the transparency slider, 
a continuous stream of change-background signals is sent to the applet. 
 This is fine, but the problem is that they alternate between 
GNOME_PIXMAP_BACKGROUND and GNOME_NO_BACKGROUND types about equally.  If 
a GNOME_PIXMAP_BACKGROUND was always sent last, this would not be an 
issue (besides some flicker), but that is not the case.

I can see no reason why a GNOME_NO_BACKGROUND change-background signal 
would be sent to an applet in this situation, but I thought I would ask 
before submitting a bug report.

I have been able to work around this bug by causing applets to wait 100 
miliseconds after a change-background signal and perform its own 
panel_applet_get_background() call, which seems to always work.

Incidentally, I am wondering if a patch to gnome-applets with 
pseudo-transparency support for all the applets would be welcome.
