glGetTexLevelParameteriv in ilutGLSubTex

[Nobody/Anonymous]

The usage of glGetTexLevelParameteriv stalls the OpenGL pipeline.
Can I suggest to execute this piece of code in ilutGLSubTex only in the debug builds?

ILboolean ILAPIENTRY ilutGLSubTex(GLuint TexID, ILuint XOff, ILuint YOff)
{
    ILimage    *Image;
#ifdef IL_DEBUG
    ILint Width, Height;
#endif
...
    glBindTexture(GL_TEXTURE_2D, TexID);

#ifdef IL_DEBUG
    glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, GL_TEXTURE_WIDTH,  (GLint*)&Width);
    glGetTexLevelParameteriv(GL_TEXTURE_2D, 0, GL_TEXTURE_HEIGHT, (GLint*)&Height);

    if (Image->Width + XOff > (ILuint)Width || Image->Height + YOff > (ILuint)Height) {
        ilSetError(ILUT_BAD_DIMENSIONS);
        return IL_FALSE;
    }
#endif

....

I think it's better leave the tests.
XOff and YOff are user provided values, they may be wrong values.
