[freetype2] master 4e1c0e8fb: Mark FT_Renderer_Class::raster_class as pointer to const

branch: master
commit 4e1c0e8fba456b2050c672c9c2c876987f03a3e6

    Mark FT_Renderer_Class::raster_class as pointer to const
    
    The `FT_DEFINE_RASTER_FUNCS` macro declares a `const FT_Raster_Funcs`.
    The address of the definition is taken and assigned to
    `FT_Renderer_Class::raster_class` which is currently `FT_Raster_Funcs*`.
    Until recently the `const` was cast away and with the removal of the
    cast there are now warnings about dropping this `const`. Instead of
    adding back the casts, make `FT_Renderer_Class::raster_class` a pointer
    to const, as is done with pointers in other interfaces.
    
    * include/freetype/ftrender.h (FT_Renderer_Class_): mark `raster_class`
    as const.
