Line 2046 in draw.c attempts to check for the thindraw flag but it seems you've moved the thin drawing into the hid (but only for lesstif). The GTK gui correctly handles thin draw of the polygons, which make the panning and zooming much faster for the sbc board. If you make line 2046 understand either the thin-draw or polygon thin draw for the lesstif gui, it will correctly draw the outline and and holes without dicing. Be sure not to break the GTK version in the process. The slowdown comes from the dicing operation used to render the polyogn. I suppose the dicing results should be cached for fast re-use since it can take some time when there are a lot of holes. It's slightly ugly because only that portion that is visible is actually diced - this is necessary for proper rendering at all zoom levels. In practice it means that whenever a polygon is clipped it should probably also be diced and stored so that rendering only clips the pre-diced poly against the viewport. ____________________________________________________________________________________ Expecting?
