Changelog:
4.4.9
* Fixed rendering issues with dispersive materials on GPU.
* Made high-quality BVH building for GPU interruptible. Fixes long lock-ups of the UI while waiting for it to finish if e.g. realtime movement was made while the high quality BVH build was running.
* Made saving of untonemapped images and layers and channels work for loaded IGIs.
* Fixed imagesaver options being stale for imageviewer.
* Removed 'Max Individual Alloc' info from OpenCL device info in the UI, since the value is incorrect on Nvidia drivers anyway, and not really relevant on AMD drivers.
* Showing delayed error messages from OpenCL in a message box, not just printing to the render log.
* Better handling of the fabric material in the OpenGL preview.
* Converting colour of specular and glossy transparent media in the OpenGL preview.
* Taking into account coating absorption in the OpenGL preview.
* Improved coating material albedo RGB output to take into account the coating film factor.
* Fixed camera focus picker tool giving an incorrect distance in some cases.
* Added z_offset to scatter UI.
* Made normalOS() and normalWS() functions work in object scatter shaders.
* Made it so that evalScale and evalCreate are both optional in scatter shaders.
* Fixed crash when setting emission_sampling_factor to zero.
* Fixed crash doing a realtime change of material type to ExitPortal with UI.
* Fixed sun colour on GPU being slightly wrong, should now be very similar to sun colour on CPU.
