[MetaHook] Load large texture from model

We need hook "GL_LoadTexture" engine function.

GL_LOADTEXTURE_SIG from hw.dll(3266) engine, can not use for other engine version.

 #include <metahook.h>
 #include "qgl.h"
 #include "surface.h"

 extern DWORD g_dwEngineBase, g_dwEngineSize;

 int (*g_pfnGL_LoadTexture)(char *identifier, int textureType, int width, int height, BYTE *data, int mipmap, int iType, BYTE *pPal) = ;

 int GL_LoadTexture(char *identifier, int textureType, int width, int height, BYTE *data, int mipmap, int iType, BYTE *pPal)
 {
     if (width >  || height > )

             buffer[(i * ) + ] = pPal[(data[i] * ) + ];
         }

         int id = g_pSurface->CreateNewTextureID();

         qglBindTexture(GL_TEXTURE_2D, id);

         return id;
     }

     return g_pfnGL_LoadTexture(identifier, textureType, width, height, data, mipmap, iType, pPal);
 }
