[Ruby] view.draw_text & X-Ray/Hidden Line Face Style

[bentleykfrog]

I ran into this issue today, reported it to google but thought I'd post it here for reference as there's an easy workaround.

If you're using the view.draw_text method in your ruby plugin or tool there's an issue when you switch the face style to X-Ray or Hidden Line. view.draw_text will only work under X-Ray or Hidden Line if you invoke some other view.draw* method. Here's my testable example

def draw(view)
	##comment out the following line to produce the view.draw_text bug
	status = view.draw2d GL_LINES, [Geom;;Point3d.new(13,10,0),Geom;;Point3d.new(13,10,0)]
	pt = Geom;;Point3d.new 13,10,0
	status = view.draw_text pt, "view.draw_text working!"
end #def

When you've attached this to a tool you can reproduce the error by running the tool with the line status = view.draw2d... commented out.

status = view.draw2d GL_LINES, [Geom::Point3d.new(13,10,0),Geom::Point3d.new(13,10,0)] tries to draw a line between two points that are in the same position (and hopefully fails to draw anything on the screen).
