Subject: [PATCH] Related: rhbz#1020712 wrong default font shown in editengine

Only in editengine could we have this fiasco.

There are two ImpEditEngine::GetScriptType's

a) sal_uInt16 ImpEditEngine::GetScriptType(const EditPaM& rPaM, sal_uInt16* pEndPos) const
this one returns i18n::ScriptType

b) sal_uInt16 ImpEditEngine::GetScriptType(const EditSelection& rSel) const
this one returns SCRIPTTYPE

Could there be a better way to ensure that mistakes will be made.

Anyway, within variant b, with an empty edit engine
ImpEditEngine::GetScriptType calls GetI18NScriptTypeOfLanguage but *that*
returns i18n::ScriptType's not SCRIPTTYPEs but when there is content then a
SCRIPTTYPE is truly returned.

Related: rhbz#1020712 more i18n::ScriptType being compared against SCRIPTTYPE

Change-Id: I5da9114a3fd8330df2b63dc9187323765d305791
(cherry picked from commit b57ffef61afd61b57087150b1a9245e21079e15b)

Resolves: rhbz#1020712 return all the selected scripts

What we want here is *all* the scripts in the range, that's the whole point of
using SCRIPTTYPE. We use this to determine the font to show in the fontbox. If
it's an exclusive script then we can show the font that that script, and if
there are multiple scripts we know to set it empty.

With the other intermediate bugs out of the way, this now appears to work
correctly.
