POV: Add primitives workspace tools icons, blurry reflections, equation based isourface ; various fixes

* fix tiny formatting of quotes, docstrings, parenthesis
* fix pov centered worspaces
* fix (revert) bad default for text block insertion
* fix primitive exports sorted by most frequent for (slight) speed up
* fix some uninitialized hairstrand root diameter variable
* fix extracted function for CSG inside vector
* fix too big size of proxy mesh for ininite plane caused it to blink
* fix end of render speach error handling
* fix max specular value to better map out under a texture influence
* fix emit, ambient, translucency shading properties UI broken post 2.8
* add workspace tools icons for pov primitives
* add a user input equation based isosurface primitive
* add micro normals based blurry reflections (glossy UI slider)
