Workbench: Change Studio lighting
This is in order to have more flexible ligthing presets in the future.
The diffuse lighting from hdris was nice but lacked the corresponding
specular information. This is an attempt to make it possible to customize
the lighting and have a cheap/easy/nice-looking pseudo-PBR workflow.
* Add cheap PBR to Workbench with fresnel and better roughness support.
This improves the look of the metallic surfaces and is easier to control.
* Add ambient light to studio lights settings: just a constant color added
to the shading.
* Add Smooth option to studio lights settings: This option fakes the
effect of making the light bigger making the lighting smoother for this
light. Smoother lights gets reflected like a background hdri.
* Change default light settings to include the smooth params.
* Remove specular highlights from flat shading. (could be added back but
how do we make it good looking?)
* If specular lighting is disabled, use base color without using metallic.
* Include a lot of code simplification/cleanup/confusion fix.

Font textbox overflow: Different methods
Sometimes the text doesn't fit. What to do in this case?
* Overflow: The default behaviour still is to overflow the text.
* Truncated: If any text box is defined we can also not draw the text
that goes outside the text boxes.
* Scale to Fit: For single-text box texts we can scale down the text until
it fits.
To support textboxes we are bisecting the scale until we find a good
match. Right now the hardcoded iteration limit is 20, and the threshold 0.0001f.
An alternative in the future would be to tackle this by integrating existing
layout engines such as HarfBuzz.
Note: Scale to fit won't work for multiple text-boxes if any of them has
either width or height as zero.
