There are several options - have you looked at grid? If you want to stick with base graphics, instead of using point glyphs, you could draw polygons at precisely the locations you specify.
A glyph is a rendering of a point, a 0-dimensional object, so it is quite reasonable to argue that glyphs should not be rescaled when rescaling a plot.
