Gap confirmed with dia-0-97 branch and GDK renderer. One benefit of the big 
renderer interface change on master is preserving the close information. 
Formerly only Renderer::fill_bezier() was known to be closed, while 
Renderer::draw_bezier() was used for closed or open stroking. Now there is 
Renderer::draw_beziergon() to stroke and/or fill.

Good guess, but it works for me with current master and the r=1.5 circle.

Again this works for me with master. Setting shape colors is certainly 
possible with dia-0-97 as well, but I can confirm the lack of color with 
the released version and your shape. It is because of a deficiency 
extracting the color name from the style string. Two workarounds:
 1) use numeric color representation
 2) use stand-alone fill/stroke attributes

With master the kludge would be to get rid of the stroke-width by using a 
path with hole. For dia-0-97 I dont know a solution as explained in
