* Rename some of the tnl->Driver.* functions to tnl->Driver.Render.*, to make itKeith Whitwell2001-07-121-2/+4
| | | | | | | | | | | | | | clear that these are owned by t_vb_render.c. Make swrast_setup opaque - it now hooks itself directly into tnl->Driver.Render.*. Add a _swsetup_Wakeup() call that does this. Update X11 (tested), osmesa and FX drivers for this change. FX compiles but is probably broken as the changes there are large. It was the only remaining driver that used the internal _swsetup_ functions for interp and copy_pv. This usage has been replaced with code from the DRI tdfx driver.
