Set Resolution for 3D Views

[#1]

Archicad users who place 3D views on Layouts for easier visualisation compared to creating renders will increase the resolution of 3D Window images on output, without workarounds. When saving images directly from the 3D window, the image can be higher-dpi than the window size. This way, users don't have to make the 3d window size bigger, which is not even possible on MacOS due to OS based screen size limitation. As we develop Physically Based Rendering, and 3D views are a common drawing type already, setting resolution to them will simplfy the workflows and provide consistancy between features.
