2097951110 [util] Change default font size of hb-view to 256 
Most common usecase of hb-view is to test rendering of short words for
testing / inspection.  Not having to type "--font-size 150" each time
isn't such a bad idea...

18c06e189b [Indic] Add Uniscribe bug feature for dotted circle 
For dotted-circle independent clusters, Uniscribe does no Reph shaping
for the exact sequence Ra+Halant+25CC.  Which also is the only possible
sequence with 25CC at the end.
