[mcclim-devel] opacity / translucency

hello, after some basic experimentation with setting the 'opacity' of various inks, and attempting to compose-in/compose-over, im unable to find an obvious way to blend freshly drawn pixels (eg. using draw-line*) over previously drawn pixels. is it at all possible using the x11 (or potentially the beagle) backend to draw transparent/translucent objects in mcclim panes? the clim reference suggests it should be, . .. if such blending is not currently supported, could anyone suggest a method to simulate it? (a partially flipping +flipping-ink+ ??) thanks, nik
