I'm porting a Qt application to JUCE and there are paths in there, that won't render correct. They are drawing a rounded rectangle with small indicaters. But the rounded rectangle looks pretty awefull, see attached screenshot. The horrizontal and vertical lines are always antialiased and 2 pixels wide. If you zoom in, you see that that the rounded corners are drawn correctly with 1px thickness.
The whole path is based on integers, so there is no way I'm drawing between 2 pixels.
