[Bug] Point display filtering not working

[OpenRift412]

Was testing out the new release and found that the point option for display filtering doesn't seem to be working at all. It seems to just be using whatever the default is.

You're right, I must have broken it with one of the recent changes before release. I also forgot to document that downscaling was changed to use convolution for all existing filters too, which means it would apply a box filter for the "point" option.

Well, luckily this isn't the most important filter, but I'll try to fix it.

I would argue otherwise, but that's ultimately up to you.

It seems to have been a simple issue, here's a quick fix until the next release:
ddraw.zip (diff.txt compared to v0.5.0)

Fixed in v0.5.1.
