Behdad Esfahbod 5d874d566f [GPOS] Fix mark-to-mark positioning when one of the marks is a ligature
This commit: a3313e5400 broke MarkMarkPos
when one of the marks itself is a ligature.  That regressed 26 Tibetan
tests (up from zero!).  Fix that.  Tibetan back to zero.

Behdad Esfahbod a3313e5400 [GPOS] Fix MarkMarkPos applied to results of MultipleSubst
This was broken as a result of 7b84c536c1.
As Khaled reported, MarkMark positioning was broken with glyphs
resulting from a MultipleSubst.  Fixed.  Test with the ALLAH character
in Amiri.

As was reported to me, glib-mkenum does not understand named enums,
so remove for now.

all our enums.

Behdad Esfahbod da97541988 [API] Allow negative font x_scale/y_scale
I was reconsidering whether y should grow down, since all three/four
times I've used this API I was tricked and got that wrong in my use.
So I was very inclined to make y grow down instead of up.  However,
considering that the font space has y up and it would be very confusing
for callbacks to work against that, I decided that what I really want
is for the user to be able to set y_scale to a negative number to imply
that user-space y grows down.

Changing x_scale/y_scale from unsigned int to int allows that, and I've
made pango to use that instead of negating glyph y_offset later.  hb-ft
however still has y group up.  I *guess* that's how FreeType works?
I'm not sure, FreeType docs don't make this clear...

I'm happy with the resolution :-).

Behdad Esfahbod c57d454acc Rename all private sources and headers to C++ files
So we can liberally use the simple features of C++ that parts of the
codebase is already using.

Behdad Esfahbod 0a4399ca22 Fix scale issues
hb_font_set_scale() now sets the value to be used to represent a unit
pixel.  For example, if rendering a 10px font with a 26.6 representation,
you would set scale to (10 << 6).  For 10px in 16.16 you would set it to
(10 << 16).  This space should be the same space that the get_glyph_metrics
and get_kerning callbacks work in.
