2017-07-25	Fix T51450: viewport render time keeps increasing after render is done.	Jeff Knox
	Reviewed By: brecht Differential Revision: https://developer.blender.org/D2747
2017-06-16	Cycles: Fix race condition happening in progress utility	Sergey Sharybin
	This is not enough to mutex-guard modification code of integer values, since this operation is NOT atomic. This is not even safe for a single byte data types. For now guarded the getter functions, similar to other functions in this module. Ideally we want to switch modification to an atomic operations, so we wouldn't need any locks in the getters.
2017-05-19	Fix T51555: Cycles tile count is incorrect when denoising is enabled	Lukas Stockner
	Now rendered and denoised tiles are counted and displayed separately.
2017-03-29	Cycles: Make all #include statements relative to cycles source directory	Sergey Sharybin
	The idea is to make include statements more explicit and obvious where the file is coming from, additionally reducing chance of wrong header being picked up. For example, it was not obvious whether bvh.h was refferring to builder or traversal, whenter node.h is a generic graph node or a shader node and cases like that. Surely this might look obvious for the active developers, but after some time of not touching the code it becomes less obvious where file is coming from. This was briefly mentioned in T50824 and seems @brecht is fine with such explicitness, but need to agree with all active developers before committing this. Please note that this patch is lacking changes related on GPU/OpenCL support. This will be solved if/when we all agree this is a good idea to move forward.

2016-12-03	Cycles: Refactor Progress system to provide better estimates	Lukas Stockner
	The Progress system in Cycles had two limitations so far: - It just counted tiles, but ignored their size. For example, when rendering a 600x500 image with 512x512 tiles, the right 88x500 tile would count for 50% of the progress, although it only covers 15% of the image. - Scene update time was incorrectly counted as rendering time - therefore, the remaining time started very long and gradually decreased. This patch fixes both problems: First of all, the Progress now has a function to ignore time spans, and that is used to ignore scene update time. The larger change is the tile size: Instead of counting samples per tile, so that the final value is num_samplesnum_tiles, the code now counts every sample for every pixel, so that the final value is num_samplesnum_pixels. Along with that, some unused variables were removed from the Progress and Session classes.

2016-05-22	Fix Cycles compile errors with GCC due to double promotion as errors.	Brecht Van Lommel

2015-06-17	Cycles: Report total and render time to the log	Sergey Sharybin
	This includes total render time spent on rendering since render() was invoked and also prints time of actual rendering (without synchronization step).

2015-01-19	Cycles: Avoid crash in statistics when canceling BVH build	Sergey Sharybin
	Also add missing render_time initialization in progress.
2015-01-14	Cycles: Ignore preprocessing time in ETA calculation	Lukas Stockner
	This patch makes Cycles ignore the time spent in BVH construction etc. when estimating the remaining time. Considering that the remaining time is calculated based on the average time per tile so far, as far as I understand it makes no sense to include the preprocessing time.

2014-12-25	Cleanup: Fix Cycles Apache header.	Thomas Dinges
	This was already mixed a bit, but the dot belongs there.
2014-12-05	Cycles: Add dedicated Progress::set_error() call	Sergey Sharybin
	Currently it acts the same as set_cancel(), but this way we're able to distinguish situations when rendering was aborted by user demand (for example pressing Esc in standalone renderer) or if something went horribly wrong (for example out of VRAM error).
2014-07-25	Cycles Bake: show progress bar during bake	Dalai Felinto
	Baking progress preview is not possible, in parts due to the way the API was designed. But at least you get to see the progress bar while baking. Reviewers: sergey Differential Revision: https://developer.blender.org/D656

2012-11-09	Cycles: persistent images option	Sergey Sharybin
	This option enables keeping loaded images in the memory in-between of rendering. Implemented by keeping render engine alive for until Render structure is being freed. Cycles will free all data when render finishes, optionally keeping image manager untouched. All shaders, meshes, objects will be re-allocated next time rendering happens. Cycles cession and scene will be re-created from scratch if render/ scene parameters were changed. This will also allow to keep compiled OSL shaders in memory without need to re-compile them again. P.S. Performance panel could be cleaned up a bit, not so much happy with it's vertical alignment currently but not sure how to make it look better. P.P.S. Currently the only way to free images from the device is to disable Persistent Images option and start rendering.
