Hi everyone,

when running

$ /opt/lo/bin/make-4.2.1-msvc -C vcl CppunitTest_vcl_complextext

on Windows 7, KVM QXL GUI via Spice I get the following failures:

C:/cygwin64/srv/dev/master-debug/vcl/qa/cppunit/complextext.cxx:98:VclComplexTextTest::testArabic
equality assertion failed
- Expected: 71x14@(0,1)
- Actual  : 70x14@(1,1)

VclComplexTextTest::testArabic finished in: 171ms
VclComplexTextTest::testTdf95650 finished in: 86ms
C:/cygwin64/srv/dev/master-debug/vcl/qa/cppunit/complextext.cxx(98) :
error : Assertion
Test name: VclComplexTextTest::testArabic
equality assertion failed
- Expected: 71x14@(0,1)
- Actual  : 70x14@(1,1)

This doesn't happen when run via a Cygwin SSH session.

I added a

SAL_DEBUG( "ID: " << rGlyph.maGlyphId << " " << rRect << " " <<
aGM.gmCellIncX << " " << aGM.gmCellIncY );

to the end of WinSalGraphics::GetGlyphBoundRect

and normalized the output using
sed -i -e 's/^debug[^ ]* //' workdir/CppunitTest/vcl_complextext.test.log

The following diff is between the SSH and GUI session:

All height values are the same, just the width and x-offsets change.

From the documentation, the provided matrix to the function is the
identity matrix, which just leaves some room for different HDC.

AFAIK HDC is driver dependent (whatever driver is used for SSH) and so
I'm not sure this is fixable at all.

So I propose disabling it also on Windows.

Any comments?
