More frame pacing options

[xenophobentx]

Is your feature request related to a problem? Please describe.
Current framepacing options: we have low latency and smooth options. Low latency for sure has some frame rendering hickups with displaying frames as per design and smooth is smooth but can cause large amount of latency.

Describe the solution you'd like
Android version has the frame pacing option "balanced" which is a very nice compromise beetween low latency and smoother stream upto only one frame of additional latency.

Describe alternatives you've considered
