vcl::Window::SupportsDoubleBuffering: respect VCL_DOUBLEBUFFERING_FORCE_ENABLE
Double buffering default is false, then can be enabled on a per-widget basis, finally this can be overriden at runtime by the VCL_DOUBLEBUFFERING_FORCE_ENABLE environment variable (so that everything is painted using double buffering). Let SupportsDoubleBuffering() also respect this variable, so code calling SupportsDoubleBuffering() can react to the runtime override, too. Change-Id: Ic9a1c00a801f6976069d7cfc47c3fa491ebc1ff0
