OK, I'm just surprised that the ZWSP here represents a word break. I really
wonder whether these ZWSP are only present in that position because of an
erroneous conversion from a non-Unicode font. In scripts that I'm familiar with
using a virama (mainly Myanmar) you would have an invisible syllable break where
you have placed a ZWSP but you would never have a word break or line break and
so you would not insert a ZWSP in that position. 

If you have use a ZWSP like this, then you have to be sure that you want line
breaks in that position in the middle of the conjunct. If you do get a line
break, then the Consonant Ya will change its shape which seems unlikely to be
desirable. i.e. you will get:

[end of some line] U+1B2D U+1B44 U+200B
U+1B2C [start of next line, rendered as normal, not as conjunct]

I am starting to look at the next generation of Graphite "NG" and as part of
this I'm experimenting with caching graphite results on a word by word basis to
improve rendering speed. I'm not aware of any scripts which require context
across a space boundary, though some do require start/end of line
contextualisation. If Balinese does require contextualisation between words (as
opposed to between syllables) then it will not be able to take advantage of such
optimisations and I will need to add special code to detect cross-space
contextualisation rules.
