Glyph positions maintain 32 bit integer part.
A glyph position when mapped from canvas space to device space may land
outside the bounds of the current 16 bit integer part of device space.
Device space is already limited to 32 bits for the integer part,
but for a short space in drawText and drawPosText it is currently
limited to 16 bits (SkFixed). Raise this limit by moving to 48.16.
This matches the current similar fix for measureText.
