Fix for bug 7467609 Bad rendering of Telugu text 

This change moves Telugu back before the fallback font. Previously it
had been moved to after it because it contained incorrect mappings of a
number of characters, including U+2212 and U+FFFD. These fonts have now
been fixed. When placed after the Droid Sans Fallback font, the glyph
count for complex script shaping exceeded the 2^16 limit, causing
incorrect rendering.

This patch depends on the fix for the Lohit-Telugu font.

         a cumulative limit of 64k glyphs. Thus, if they are placed after the

         large fonts such as DroidSansFallback, they are likely to render

         incorrectly. Please use caution when putting fonts toward the end of

         the list.
