Hello Behdad/Jonathan,

Finally managed to get a Uniscribe rendering to test 'RA' and sub-base
'LA'. Meera and Rachana fonts render similarly using harfbuzz and
Uniscribe, but AnjaliNewLipi differs.
With AnjaliNewLipi, Uniscribe renders all the 'RA' cases (example
'സ്പ്രി') and the sub-base 'LA' (example 'സ്പ്ലേ') correctly. Please
find the latest test results here:

Uniscribe rendering for comparison:
