New issue 1118: [experimental] Camera focus and positions should work correctly when passed YTArray instances
Right now the focus and position properties don't handle data with units being passed to them. They should have some logic to handle converting the data to code units if we pass them a YTArray.
New issue 1115: [experimental] add in keyframes for making complex camera paths with scene VR
something long talked about is the possibility of doing more camera paths than simple rotation, pans, and zooms. the VR refactor YTEP lays the groundwork for a timeline object and identifying keyframes (ie camera location, focus, orientation, lens type, transfer function, etc.) along that timeline before use a continuously varying function (ie spline) to connect those keyframes into a continuous path. putting this here as a placeholder for implementing this.
New issue 1114: [experimental] opaque sources balanced with render sources
Using opaque sources (e.g. points and lines and grids) with render sources (e.g. gas VR) tends to result in either seeing just one or the other out of the box. It takes a lot of work to balance the opacity of the different sources, and it is not documented how to do this. I think we should potentially provide better default opacities associated with these so as to make both points and gas visible in the same rendering out of the box. I think we should also work on documenting easy ways to change the relative opacity of different sources to highlight one source or the other in the rendering.
