  [type42] Fix new memory leak.
  
  We need to inverse inheritance of FT_GlyphSlot_Internal so that we
  have a chance to free the rendered bitmap from the parent slot.
  
  * src/type42/t42objs.c (T42_GlyphSlot_Init): Remove the internal parts
  of the child `ttslot' and replace it with the parent structure.
  (T42_GlyphSlot_Done): Updated accordingly.
