-Fixing irradiance artifacts in Adaptive BSD.
-Fix for Presto hang in bucket rendering due to bevel mapping yielding zero normal vectors.
-Fixed displacement from parallel view that could yield no intersections at all.
-Fixed sky color in Presto when view is exactly vertical.
-Nlm Denoiser: Added Fiji, Capeverde AMD family compilation.

-Added option to Edit Thea XML Model file - it will be saved as .mod.thea
-Fog Density accepts values below 1.0 now
-Bump map slider works within 0-100% range, but accepts higher values entered manually

-A warining sign with a tool-tip displayed when a device priority is higher then 'Low'
-Logging of the plugin start-up and a first rendering done in Temp(tmp)/Thea4SU/Thea4SU_Session...log & TheaEngine.log folder. Useful for debugging

Material Editor:
-Duplicate Layer - right-click function added
-When switching from Bitmap Texture to SketchUp texture parameters are preserved (Normal/Bump/Tonemapping...)
-Red,Green and Blue Shifts added to Texture Tonemapping
-Layered texture can be removed from texture selector as any other texture type now
-Layer mask can be set now either to Bitmap or Procedural
-RGB or HSV value modification updates also a "current" color in ColorPicker

Fixes:
-Improved behaviour of SliderValue controls - they do not change when hoovering above them with left mouse button pressed
-Scene settings are always loaded when new scene is selected from a list (not only when a check-box is marked)
-Material Presets: Fixed bug with external textures not being found in an immediate or '_files' sub-folder
-FBX Materials Editing : Fix for erroneous material selection from a list in case of some models
-Fixed issues regarding unicode texure paths/names. It was affecting locale like Chinese. Bitmap Textures could not be loaded for example, resulting in black materials
