remove this wrong-direction broken stuff. I don't see the original problems
anymore to see if they need an additional fix of some other kind.

another stab at tdf#91393

block paints only if the new requested size is larger than the original and
unblock on explicit expose events as well as configure ones

commit e6a1956034c98204e30b0ca40330249d6f6f8155

tdf#91301: Don't cache incomplete tabs.

After introduction of the Idle processing, something has changed so
that the underlying GetGdkWindow() does not update its size fast enough;
even though the gtk_window_resize() is called before the Window::Erase()
(that actually paints the background) etc.


i.e. if you resize the window slightly when cpu is 100% it'll jump back down to
low load afterwards

I can't reproduce with:
Win10x64
Version: 5.3.0.0.alpha0+
Build ID: 3287bc2f91438085b7604773d5e0346fc3c3f452
CPU Threads: 4; OS Version: Windows 6.19; UI Render: default; 
TinderBox: Win-x86@42, Branch:master, Time: 2016-09-18_05:11:16
Locale: es-ES (es_ES); Calc: CL
Version: 5.3.0.0.alpha0+
Build ID: 4c70a1aa079872b8f1966bd398e924dc1d1a
CPU Threads: 4; OS Version: Windows 6.19; UI Render: default; 
TinderBox: Win-x86@42, Branch:master, Time: 2016-09-22_06:54:24
Locale: es-ES (es_ES); Calc: CL

In my I3 2-3% of cpu usage.

Maybe only Linux issue.

There are some things really slow first time LibreOffice is open, more visible
in master, i.e.  selecting in context menu character or paragraph options, or
in calc the format option.

Reported bug, perhaps in relation:
https://bugs.documentfoundation.org/show_bug.cgi?id=98132
Format cell dialog very slow to pop up

I can't find now but I think there was some bug about the slowness on load font
list first time.
