I thought about this some more, and I believe my original recommendation was
correct.  Because floatWidth measures these glyphs (it runs in both
calcMinMaxWidth and findNextLineBreak), we need to make sure these glyphs have
zero width in the low-level Font rendering routines.  Otherwise widths will be
computed inaccurately.

This does not preclude us from adding code to bidi.cpp to avoid having them in
the rendered runs, but they also can't be part of measurements either.

Taking this bug since I own the corresponding Radar.
