Border style unfinished

[ArtHome12]

The library understands separate styles for the top, right, bottom and left lines of the border, different types of fill (groove, ridge, etc.), but the drawing is implemented primitively - the same as top border and only solid.
The existing code of Sources\UI\Style\style_background_renderer.cpp:

	void StyleBackgroundRenderer::render_border()
	{
		int num_layers = style.array_size("background-image");
		if (!get_layer_clip(num_layers - 1).is_keyword("border-box"))
			return;

		StyleGetValue style_top = style.computed_value("border-top-style");
		if (style_top.is_keyword("solid"))
		{
			Colorf color = style.computed_value("border-top-color").color();
			if (color.a > 0.0f)
			{
				auto border_points = get_border_points();
				auto padding_points = get_padding_points(border_points);
				Path border_path = get_border_stroke_path(border_points, padding_points);
				border_path.fill(canvas, Brush(color));
			}
		}
	}

It is necessary to implement:

• separate border drawing (top, left, right, bottom);
• support for all styles (thin, medium, thick, dotted, dashed, double, groove, ridge, inset, outset).

Maybe someone has already done this in his code and just need to copy-paste?

I believe that Judas did some work on border top/bottom/left/right in his UICORE github project.

If i remember correctly it wasn't ported to clanlib because there maybe performance issues for drawing simple borders. (This hasn't been checked).
