Summary: doesn't display big images on windows

Initial Comment:
Hello,
Hugin doesn't display big images on the CP editor panel
on Windows2000.
I tried all versions from 0.3 to 2004/03/19 snapshot.

Hugin can display 2000x1300 image up to 200%, but on a
7800x5200 image it will display the image up to 50%.
75% zoom and more will display only gray, without any
error.

The control point are however display (the normal color
circle on the gray background)

It isn't a memory related problem, because at any zoom,
hugin use roughly 2x the size of the complete 100%
image (more some overhead) (or 1x if the same image is
selected on right and left panels) without problem.

It seems to be a problem of redrawing image.
In fact, there are some weird thongs when changing zoom :
On a 7800x5200 image :

fit window -> 25% or 50% : redraw OK
25% -> 50% : doesn't redraw, but by moving the bars the
image appear
50% -> 25% : may redraw, partially or totaly. Moving
the bars gets you the image
fit window -> 75% or more : redraw gray. Moving the
bars gets you only gray (and the control points)
other -> 75% or more : doesn't redraw. Moving the bars
gets you gray

Anyway, the horizontal and vertical bars seem OK (there
size change accordingly with the zoom)

Sorry for this long description, but I hope it may help.
