// 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 ?
