* allow user to disable continuous tuning, viewer will try to reach a stable target then stop tuning.
* Save/Load graphics presets.
* reset to graphics defaults
* alter layout to be more intuitive, guided by user feedback
* various minor grammar and spelling consistency changes
Should fix the crash to desktop behaviour when autotune was used and preferences not previously opened.
Also cleans up various warnings where unsupported params were used on certain elements.
Also adds the ability to see the "revised" render time rather than the original. This can be confusing when auto tuning so defaults off.
Cleaned up some text
* enables autotune setting panel
* adds help_topic fs_performance_floater (placeholder page created)
* adds new optional control of maxnonimpostors based on distance from camera.
- cleanup and ratioanlise code altering the settings.
- rename to make units more obvious
- make slider logarithmic to make the req'd range more practical.
make the auto-tuning more robust and a little less trigger happy.
- fix incorrect logic that blocked maxnonimposter control from working
- Zoom to Avatar instead of cam to avatar for consistency rather than correctness.
-open phototools not phototools_camera.
