Subject: [PATCH] now have function to get window style based on FreeGLUT's
 stateflag (fgState.DisplayMode) so that window decoration specification is
 only in one place in the code. Also, glutGet(GLUT_WINDOW_BORDER_WIDTH); and
 glutGet(GLUT_WINDOW_HEADER_HEIGHT); now return the right sizes, i.e., taking
 the display mode into account, for the border and caption when no window is
 created yet
