Bad on-screen rendering of scaled 1px-raster graphics

[Norbert Nemec]

To draw color-scale bars for scientific plots, I use
raster graphics of the shape 1x256, which are then
scaled to the physical width of the colorbar (several
mm). (see attached file)

Working on this kind of heavily scaled raster graphics
results in strange behavior of the on-screen rastering:
try to zoom in, scroll, mark the raster graphics and
resize it. You should see how the color of the graphics
do not perfectly follow the size of the frame,
producing artefacts that change with scrolling.

I can confirm this on WinXP latest build.

When a small image is imported it seems to leak out of its bounding box or retracts in as you zoom in/out or scroll

I repro the transient artefacts when resizing. They disappear after zooming a notch. Didn't see any other weirdness.
