Feature to print screen/ export 2D image with defined resolution.

The ability to export "solid view" with defined resolution within the canvas has numbers of benefit, such as...

1. No rendering time required to create ID Mask with high resolution.
2. Benefit to create simple diagrams (Architects often use in presentations)
3. Useful for graphics editor (e.g. Photoshop) as the already established "Solid view" provide a lot of potentials in creating simple good looking diagrams. (outlines, shadows, x-ray, AO, etc.)

This function is similar to SketchUp's "export > 2D graphic" for the reference.
