Vegas image issues

[SKU]

Two things

1) How do you set the image to be source size? I've been using the pan/crop and just making the view space to be as big as possible, but it's still bigger than the source image ever is.

2) When in pan/crop my images will move as far vertically as needed, but they disappear before hitting the edges horizontally. Nothing I've tried has been able to change this.

Thank you!
