Meera has a different Ascent and Descent values compared to other
fonts. Meera has ascent and descent as 1147, 901. Rachana has it as
1638, 410. This is to accommodate the characteristics of Malayalam
script. And this change results in smaller sizes compared to other
fonts. The fontconfig rule was added to offset small size for Meera
compared to other fonts.

Pango/GTK applications understand the scaling directives and scales up
Meera font properly. The ideal solution is to have m17n/emacs
implement fontconfig scaling feature.

Thanks
Praveen
