The EditEngine decomposes it's content mainly to
Prmitives (there is still a direct paint mode used
in rare remaining cases which we not yet got rid
of). For TABs the special case for 'extended' TABs
(see format/paragraph/Tabs, FillCharacter) was
handed through all layers using method DrawingTab,
put into a DrawPortionInfo and held at the text
primitive (TextSimplePortionPrimitive2D). While
for direct paint the expansion was already done in
ImpEditEngine::Paint anyways (and always painted,
independent from bStripOnly what was unneccessary
and I corrected that, too) it had to be done for
text paint in VclProcessor2D for each repaint.
This is not needed, so now the extended text
created in EditEngine decompose gets used.
This makes a lot of stuff simpler, including
EditEngine/Outliner and some involved classes.
If it somehow should show that it might be
necessary to do that for each paint it should
be done in the obvious way then - using an own
primitive that creates the expansin in the
decomposition (and buffers it).
