Explicit LRO, RLO, etc. in FT2 patch

[Tony Graham <Tony Graham ireland sun com>]

With basic-ft2.c, formatting characters in the range U+202A to U+202E
(i.e., bidi formatting characters LRE, RLE, LRO, RLO, and PDF) ends up 
with Pango trying to find glyphs for the characters and failing.  The
result is the .notdef "glyph" and a big gap in the line.

The following patch expands the list of characters that are
effectively passed over as glyphs to include all non-graphic
characters.

Regards,


Tony Graham
