Lack of a user defined margin

Lack of a user defined colour pad

This bug report refers to the lack of a user defined colour pad, the empty area around a QR code.

Colour padding

Machine reading improves when codes have a large padded area around them, in the same colour as the very thin margin as defined in existing sources.

int margin = (obj_w - scaled) / 2;

Suggestion

To introduce a user defined padded area, a parameter could be added wherever graphic size is referenced (in buffers, allocation, and construction.)

Pull request pending

I've solved this problem and will submit a pull request called Colourpad Addition 1A.

Close this if pull request #9 is merged, thanks.

Or just close it regardless, if you think the problem does not exist. No offense taken if you do that.

Thanks, I commented on the PR.
