  [truetype] Reset the IUP-called flags for each subglyph.
  
  This fixes fall-out from 7809007a5b88b15, where the composite
  accents were no longer hinted.
  
  * src/truetype/ttgload.c (ttloader_init): Move the IUP-called flag
  initialization from here...
  * src/truetype/ttinterp.c (TT_Run_Context): ... to here.
