Fix crash when text contains too many directional chars
In case a text to be layouted contains more than 128 directional characters
it causes the application to crash
The function initScriptAnalysisAndIsolatePairs() collects information of
RTL/LTR chaaracters into vector "isolatePairs". The size of the vector is
capped to 128. Later the function generateDirectionalRuns() iterates
the text again and tries to access items from the previously capped vector
above the upper bound.
