Drag canvas disabled inside Image Filter Nodes

[laffan]

Information:

• Chainner version: [e.g. 0.11.0]
• OS: [e.g. Windows 10, macOS 10.13]

Description No way to drag canvas if inside "Image File Iterator" node. These nodes can easily cover the entire work area, and the only way I've found to navigate internal nodes is to use the "Fit View" button.

(Thank you so much for making this - it's an absolutely godsend. )
