Re: gtk+ and gtk-engines slow

On 23 Jan, kevin scribbled:
->  Well, If you dont use the cache, the pixmap engine is worthless. It is far to slow
->  to use even on a dual 350. With the cache it is at least useable.

please look at gnome-libs/libgnomeui/gnome-init.c: line 198
                        gdk_imlib_set_cache_info (0, 1);

it checks if preferences say to disable the imlbi pixmap cache then
sets this - what mgiuel doest realise is ther ALREAYd IS an IMLIb
PREFERENCES PROGRAM

imlib_config

it lets the usre turn on and off the pixmap cache and image cache and
set their sizes and everything - thsi overrides any of that and makes
it useless. This is what I woudl call nasty programming. EVERY gnome
app has now as a reult pixmap caching turned off because there is no
way for a user to turn it on - and the imlbi config program is useless
due to this overriding of user preferences. Imlib has and has had user
prefs since the dawn of time for a reason.

I'm going to disable this code in gnome-libs and I don't see ANY good
reasonf or it to be re-renabled. it only leads to horrendous
performance issues.
