Hidden minimum values for sizes

[Vortelf]

Using version 0.1.1.

The set Width and Height are positive, but probably not enough for the app to create a gif. The error is misleading.

Ah yeah, this has to do with the Padding, great catch.

[maaslalani]

We subtract 2 * Padding from the width and height so the height would be negative in this case. I will fix!

To fix this on your end you can:

Set Padding 10

I'll also ensure that the numbers cannot be negative on VHS' side.
