Hi Mirek,

I'm using the wonderful new Xform2D::Map() to render a raster map image over a specific area with specific corner coordinates. This is a great feature, but BufferPainter::Fill(image) suffers from edge effects at the borders of the image fill. The fill leaves narrow gaps between the filled triangles.

I am afraid this is just a feature of antialiased rendering. Problem is gradual composition of those edge points I think.

FILL_FAST unfortunately is still based on the same method, just rounding values to 0/1.
