Hi, Phil.
Looks like there is workaround for this and now it should be removed.
I'll take a look at it.

Sergey,
This needs another look. Although it fixed some clearly broken cases,
there is a rotated tab pane label option in SwingSet2, and it turns
out that at least for me that was working *before* the fix and now
its broken. So I suppose that there are 2 pieces of code interpreting
the sign of the advance with different expectations.
Since only Aqua does that rotation for the tab pane label, I think the
special case is there .. where it likely expected the original CT
coordinate system.
The bug report in the test case uses custom rendering so
won't fall into that case as had seemed likely from the synopsis.

I think this fix is fine. In the other rasteriser cases we use
(T2K, freetype) we also flip the sign of the y advance as it is stored
as the image y advance. It looks like this was just missing here.
This change should then only affect the final glyph rendering.

Hello,
Please review the fix for jdk 8.
On OSX advanceY in the glyphInfo is inverted.
It is used to increment position when the glyph is drawn as part of
a string of text:
@see DrawGlyphList.c.setupBlitVector():
....
for (g=0; g<len; g++) {
ginfo = (GlyphInfo*)imagePtrs[g];
.....
FLOOR_ASSIGN(gbv->glyphs[g].y, y + ginfo->topLeftY);
.....
y += ginfo->advanceY;
}
advances are initialized in the CGGlyphImages.m via
JRSFontGetAdvancesForGlyphsAndStyle().
Note that JRSFontGetAdvancesForGlyphsAndStyle use "strike->fTx" and
the origin of this transform is relative to the bottom-left corner
baseline. So we should pass "strike->fAltTx" to the
JRSFontGetAdvancesForGlyphsAndStyle(Not sure is it ok or not) OR to
invert the received advance.height.
