Color alpha channel

[emux]

Hi,

Does Mapsforge support alpha channel in the RGB color declarations at render theme xmls?

Because when I try to fill a polygon with:
<area fill="#ffff80" stroke="#000000" stroke-width="2.0" />
all are correct, as seen at attached sample1.png

But when I try with alpha channel:
<area fill="#80ffff80" stroke="#000000" stroke-width="2.0" />
as seen at attached sample2.png, crossing lines exist under the semi-transparent polygon.
Lines that form squares that are smaller than debug tile squares.

Regards.
