Higher graphics quality when saving image

[olibclarke@…]

The following bug report has been submitted:
Platform:        Darwin-18.6.0-x86_64-i386-64bit
ChimeraX Version: 0.9 (2019-06-05)
Description
Enhancement request: temporarily switch to higher graphics quality when saving an image.

Rationale: Using ChimeraX on slightly older hardware with large molecules can give pretty low framerates, but switching the subdivision level to 1 makes the experience a lot more fluid (at the expense of chunky graphics). I'd like to be able to manipulate the model in this mode, but whenever I save an image have it use a higher subdivision level when taking the actual image (without the user having to explicitly change it and then change it back). This could maybe be set as a preference, "default subdivision level for images" or similar.

Cheers
Oli

There could be a preference for this. I think the default would be use the same subdivision as on-screen. I think very few users would find this preference and use it.
