Mandelbulber v2.08
Together with @zebastian , @mclarekin and @bermarte we have finished new version of Mandelbulber.
Development of this release was focused on implementation of material management and texture mapping. From now there is possible to define many different materials and assign them to fractal and primitive objects, like it is possible in most of 3D modeling applications. Materials can use textures for color, luminosity, diffusion, normal maps and displacement maps. Texture mapping uses bicubic interpolation together with mipmapping.
For fans of 3D printing there is function to export fractal as point cloud (series of images with fractal slices)
There is about 20 new fractal formulas and many new small features, improvements and bug fixes.
What is new?
- Materials: Added editor for materials as a separate dock
- Materials: Added real-time preview for edited material
- Materials: Added Material Manager dock which can be used to select, add, remove, load and save materials

- NetRender: Fixed bug: - crash - when client version was wrong it cleared message buffer after client was deleted (with message buffer)
- UI: Added auto-refresh function. There is new checkbox just below RENDER button. This function should be good for experimenting with different fractal parameters, because image will re-rendered automatically when any parameter will be changed.
- UI: Added image quality presets
- UI: in preferences dialog now there are two tabs: general, image
- UI: preferences dialog and animation player now opens only once (bring to front, when already opened)
- UI: added option to load thumbnail cache from server (mandelbulber.org) which speeds up displaying previews for examples

About queue tool:
Queue tool allows to render a collection of settings files in the background.
While the list of settings files is being rendered, you can continue to work in the main window and also add more settings to the queue.
Methods to manage queue:
- by adding items using Add current settings button
- by editing queue.fractlist file
- by puting files into queue folder and use button Add orphaned
- by adding single settings or lists using command line interface
Temporary settings files are stored in $HOME/.mandelbulber/queue folder and the list is in $HOME/.mandelbulber/queue.fractlist
The queue can be rendered in another instance of Mandelbulber program, as the queue is shared between applications. You can also launch another Mandelbulber from command line interface with -q option. Then this application will watch queue and render automatically all new items.
Result images are saved into $HOME/.mandelbulber/images directory (or another if it's specified in application preferences.)
