If nullDC is set to render at non-native resolution (ie. not 640x480), 
horizontal and vertical lines often appear through 2D images. See pictures for 
an example.

The lines do not appear if nullDC is set to native 640x480.

Tested with r78.

Thats more of the game not supporting 'properly' aligned pixels, so the extra pixels rendered by nullDC end up getting wrong texture data (that is not visible on the native resolution) I was thinking to add a 'safe' upscale mode that addresses this ... but never got around it. This is more-or-less a direct consequence of hi-res rendering, and many sprite based games are affected by it ...
