Hi,

I have submitted a patch for review:

    https://gerrit.libreoffice.org/1716

To pull it, you can do:

    git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/16/1716/1

Resolves: fdo#59182 make the special character dialog behave

squashed combo of four commits to fix fdo#59182

Related: fdo#59182 stop SvxShowCharSet resizing itself

instead of resizing itself when given a size, leading
to lots of flicker as the widget fights the layout,
instead accept the given size, center the drawing in
that area, and tweak the cell highlight drawing
code to fill that extra gap space when edge cells
are selected

(cherry picked from commit 3c8d3ef10267fb0a50686f49c15a3e4ab35503d1)

Related: fdo#59182 make SvxShowText::GetOptimalSize match its SetFont logic

SetFont takes the window size to determine the best font size, so reverse that
SetFont logic to get the desired optimal window size.

(cherry picked from commit 463f2d4fe211e991d551be67be74cf2090afdb7e)

Resolves: fdo#59182 make the special character dialog behave

lock down the sizes of the widgets which depend on the (variable) font in terms
of widgets which are invariant so that they don't jump around to their optimal
sizes as the selected font changes.

(cherry picked from commit f1088250485fa91b4131102c5275e73653bc0c2c)

use the theme width for the scrollbar, not a random 16 pixels

(cherry picked from commit 26af997c55106fd067b32caaceedde3f2c10c1dc)
