Reporting a graphics bug - stamping an image does not scale the image if its width is only one pixel. (there are other plotting issues too as can be seen in the demo but the scaling is a major one)
btw it behaves the same whether the image is a bitmap or a vector. When run in @procd's compiled version it behaves the way it is supposed to, confirming this is a scratch runtime bug. Workaround suggested by @MegaApuTurkUltra seems to work: http://scratch.mit.edu/projects/31812806/
