preview widget in queue dock.
- Changes from Version 2.11:

* Fractals: Cleaned up names of fractal formulas.

* Fractals: Corrected MixPinski code.

* Fractals: Corrected Menger4D and Menger4D Mod1 code.

* Fractals: Corrected Abox - Mod1 and Mod2 code.

* Fractals: Upgraded the reset button on fractal tab. It now also
resets iteration number and range, weight, add global C constant
and check for bailout conditions.

mode.

* Fractals: Updated transform Spherical fold 4D.

* Fractals: Updated Menger Cross KIFS.

* Fractals: Added linear_DE_offset parameter for fine tuning of
distance estimation of IFS-like formulas.

+ T>Scale Vary Abox.
+ T>Spherical Fold CHS.
+ T>Spherical Fold Parab.

* Shaders: Added rotation and scale of background texture.

* Shaders: Added background texture offset sliders.

* Shaders: Added HDR blur post-effect. This is a soft blur which
can improve quality of Monte Carlo DOF effect or can be used as
a standalone effect.

* Shaders: Now all effects (including SSAO) are rendered using
floating point image buffers (better HDR quality).

* Shaders: Image brightness, contrast and gamma can be corrected
without re-rendering of SSAO and DOF.

* Shaders: Removed redundant HDR DOF option (now DOF is always
rendered as HDR).

* Shaders: Optimized Monte Carlo DOF algorithm (50% faster). Now
it uses statistical noise estimation to determine the number of
needed samples.

* Shaders: Fixed bug in algorithm for reflection calculation.

* Image: Added full screen antialiasing to the rendering
algorithm.

* Image: Added the option to save stereoscopic left and right eye,
in separate image files.

impact on rendering time. Now the distance threshold is
calculated 10 times more accurately.

* UI: Added the option to detach rendered image from main window.
It allows for the use of two displays.

* UI: Font sizes and widget sizes adapts to screen DPI and size.
User interface is displayed properly on 4K high DPI displays.

* UI: Added dialog box for hybrid/boolean fractals. When any tab
is selected with index > 1, then a message appears with the
option to enable hybrid or boolean fractals.

* UI: Detached rendered image can be displayed in full screen mode.

* UI: Added the option to display thirds and golden ratio grid.

* UI: Formulas can be searched in formula combobox.

* Voxel export: Mesh export uses much less memory.

* Voxel export: Parallelized mesh export. Now it uses all CPU
cores, so it\'s much faster.

* Voxel export: Optimized mesh export. Voxels are pre-calculated
before meshes are calculated. Calculation speed is 8 times
faster.
