Utilise full space when displaying networks with a size limit

[bcd00]

Currently, the sample networks must be displayed at a resolution less than 2880x1616 otherwise they suffer distortion. So when a user's intent is to have the network utilise the full space, it cannot, as it is currently limited.

A fix allowing these limited size networks to be displayed, centred in the space but still of limited size, would provide the user with something closer to their expected behaviour.

This would also mean the short-term fixes of providing warnings to the user could be replaced with what is more desired functionality.
