// DESCRIPTION:
// Quick interface hack for selected face interface
// this one really needs more work, but I'm in a hurry with TexTool

#ifndef __ISELECTEDFACE_H_
#define __ISELECTEDFACE_H_

#define SELECTEDFACE_MAJOR "selectedface"
// v2.0
// support for multiple faces selection (first use in textool v2)
// using the g_ptrSelectedFaces indexes, get the face_t* with GETFACE
// still relies on the _QERFaceData*, unless you cast the face_t* to do your own stuff
// removed PFN_TEXTUREFORNAME, it's in the IShaders API now

//++timo TODO: this interface needs some cleanup with the new texture / shaders interface

// number of selected textures
typedef int   (WINAPI* PFN_GETSELECTEDFACECOUNT) ();
// retrieve the corresponding brush_t* (we need it when we need to explicitely rebuild stuff)
typedef brush_t*    (WINAPI* PFN_GETFACEBRUSH) (int iface);
// retrieve a given face_t*
typedef face_t*     (WINAPI* PFN_GETFACE) (int iface);
// winding_t is assumed to have MAX_POINTS_ON_WINDING allocated and waiting
typedef int             (WINAPI* PFN_GETFACEINFO)               (int iface, _QERFaceData*, winding_t* );
// tell editor to update the selected face data
typedef int             (WINAPI* PFN_SETFACEINFO)               (int iface, _QERFaceData*);
// retrieve the texture number to bind to
typedef int             (WINAPI* PFN_GETTEXTURENUMBER)  (int iface);
// retrieving some texture information
typedef void    (WINAPI* PFN_GETTEXTURESIZE)    (int iface, int Size[2] );
// straight func pointer to Select_SetTexture
// last parameter must be casted to an IPluginTexdef
typedef void    (WINAPI* PFN_SELECT_SETTEXTURE)         (texdef_t *texdef, brushprimit_texdef_t *brushprimit_texdef, bool bFitScale, void* pPlugTexdef);

// NOTE: some things in there are not really related to the selected face
// having some stuff moved into a textures-dedicated part ?
