DIY Laser levelling using webcam and laser level

[Sasquatch]

Yes I'm running it under windows.
If I only change resolution to anything above 640x480 in settings.java it crashes saying that correct resolutions are 174xsomething 320x240 and 640x480
Defining custom dimension as per sarxos manual and FAQ(look at my pull request) allows to select any resolution. I tried 4000x3000(max res of my sensor) but image quality suggested it was still 1280x720, makes sense.
Maybe defining custom resolutions and then autos election would work?

The trouble with asking for a custom large resolution is the camera encoder chip can choose to scale it for you if it is larger than the sensor. It seems there is no reasonable solution without forcing a windows specific driver which will actually query the camera for the supported resolutions. Will look into this when I have more time. Almost all cheap cameras makers lie about the resolution of their sensors as well so we can't rely on the user inputing whatever resolution is 'written on the box'.

I did look at your pull request, but I don't think it works generally for everyone as if you request a non-native resolution the camera chip can choose to scale it for you.
