Re: [PATCH v2 0/1] MR10704: Display invalid Indic syllables

[समीरसिंह Sameer Singh (＠ss141309)]

For `lex_Matra_pre` vowels (such as `ि` ) the dotted circle should appear after the vowel sign.

I had  this snippet for `mark_invalid_combinations` in my attempt to solve this, maybe this could help?

```c
if (is_invalid)
        {
            original_clust = pwLogClust[i];
            insert_pos = g;
            if (unicode_lex(pwcChars[i]) == lex_Matra_pre)
                insert_pos = g + 1;

            insert_glyph(pwGlyphs, pcGlyphs, cChars, write_dir, invalid_glyph, insert_pos, pwLogClust);

            if (insert_pos > original_clust && write_dir > 0)
                for (j = 0; j < cChars; j++)
                    if (pwLogClust[j] == original_clust + 1)
                        pwLogClust[j] = original_clust;
            g++;
        }
```

There are also some indic vowel signs such as `ൌ` or `ৌ` where the dotted circle should appear in the middle.
