Created attachment 572489
  --> https://bugzilla.redhat.com/attachment.cgi?id=572489
Contains JPEG of attestation from printed book, PDF of current and desired
appearance and TTF of replacement glyphs

Description of problem:

The SHI SHII glyphs in Lohit Tamil font need to be corrected. In both cases the
vowel sign is not correctly positioned over the consonant. Further in SHI the
vowel sign does not attach to the consonant at all. 

Version-Release number of selected component (if applicable):

2.5.0

How reproducible:

Use Lohit Tamil font.

Steps to Reproduce:
1. Type ஶி ஶீ by selecting Lohit Tamil font.
2. Zoom to large size. 
3. Especially note the minute gap between SHA and VS-II.

Actual results:

You can see that the described problem exists.

Expected results:

The vowel sign should be correctly positioned w.r.t. the consonant and it
should correctly attach to the consonant.

Additional info:

Currently within the SHI SHII glyph of the Lohit Tamil font the contours for
the vowel sign are separate and not unified with the consonant's contours. This
causes overlapping nodes which is not recommended.

Furthermore the RSB of SHI is zero, which is inappropriate. Compare the RSB
values of glyphs of other consonants + VS-I.

I have modified the glyphs by taking the position of the vowel signs and the
RSB values of PI/PII (PA + VS-I and VS-II) as a model since the right-side
contour shape of PA is closest to that of SHA. I have provided glyphs with
unified and non-unified contours. Please find it in the attachment.

I recommend to use the unified contours and have only given the non-unified
contours in case you wish to do any other adjustment of positioning (unlikely).

I have also provided attestation for the actual appearance of SHI/SHII as seen
in printed books,

I have checked this font and the Classical equivalent and the actual reported
problems for SHI and SHII are now fixed. 

I notice that you have slightly modified the contours of the leftmost section
of the glyphs and especially there is one extra warning point in the SHII glyph
which was not there in my replacement glyph or the previous version, but those
are non-issues IMO.

So I guess it's OK to close this bug, but I think you do that only when you
actually release the fixed version so I'm not doing it myself.

Thanks!
