Subject: - Made miniswig support HSQUIRRELVM arguments (and realized it was not needed
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f1e15f44f709d6b4fa45e858dc12d7d701ae8ddc;p=supertux.git

- Made miniswig support HSQUIRRELVM arguments (and realized it was not needed
        later :)
- added a text object for scripts to use and extended the example for it
- removed the pointless uint32_t effect parameter from all the draw methods.
  Simply use DrawingContext.set_effect if you need it.
