    gl-display: Call glBindTexture() on every frame
    
    glBindTexture() changes global state, so if anything else uses OpenGL
    textures, it also corrupts RetroGLDisplay state. Calling it every time
    in retro_gl_display_load_texture() ensures that we're always working with
    the right texture.
