REQUESTING REVIEW: Correct cursor handling for Sinhala

[Harshula <harshula gmail com>]

Hi,

I've only recently looked at Pango's cursor handling code, hence could
those who are more familiar with this area please review this patch?

I will open a bug once the reviewers are happy.

Patch:
http://cvs.savannah.nongnu.org/viewvc/*checkout*/sinhala/patches/pango-1.16.4-cursor-position-sinhala1.patch?root=sinhala

Testcase:
http://cvs.savannah.nongnu.org/viewvc/*checkout*/sinhala/patches/cursor-position-testcase.txt?root=sinhala

Changelog:
---------------------------------------------------------
* BUGFIX: Correct the broken Repaya handling code.
* BUGFIX: Consonant clusters do NOT result in implicit conjuncts in
SINHALA orthography.
* The cursor should treat as a single glyph:
    SINHALA CONS + 0x0DCA + 0x200D + SINHALA CONS
    SINHALA CONS + 0x200D + 0x0DCA + SINHALA CONS
---------------------------------------------------------

cya,
