Nuke: fixing render creator for no selection format failing

[jakubjezek001]

Description

When use selection was ticked off the creator was failing as we could not retrieve format width and height from selected nodes.

Solution

Getting width and height was added to tray and if fails it will get format from root actual format

Testing notes

1. open nuke and in workfile create version (if you are in untitled script)
2. open Creator and chose Create Render Write
3. tick off use selected
4. hit create and write node should be created without troubles.
5. Look inside of the created node (ctrl+enter) and look into properties of Crop node
6. width and height should be the same as it is set on script's actual format (with mouse over node graph window hit s and look down to format)

When I create the write node with unselected use_selected it creates a render node which is no connected to the previous. Is this correct behavior?

yes that is expected behaviour. Is `use_select is not ticked of it is ignoring what ever is selected and therefore it is not connecting to it. So this works perfect ;)
