2016-09-19	OpenGL: software renderer for old Mac GPUs	Mike Erwin
	We raised the minimum to GL 2.1 in Blender 2.77, and dropped support for older GPUs (pre-2012 Intel mostly). On Windows you get a popup message, but on Mac we simply crashed. Every Mac has a builtin software renderer for GL 2.1 so let's use that when the GPU is not capable! Run blender --debug-gpu to see version detection & software fallback.

2016-09-18	Cycles: Fix update of subdivision meshes when global dice rates change	Mai Lavelle
	When subdivision settings were moved from meshes to objects this was missed, should work fine now.
2016-09-18	Cycles: Soft minimum for dice rates	Mai Lavelle
	Use 0.5 as a soft minimum for dice rates to help from setting them too low. Lower values can still be set by typing in the value.
2016-09-18	Cycles: Adaptive isolation	Mai Lavelle
	Idea here is to select the lowest isolation level that wont compromise quality. By using the lowest level we save memory and processing time. This will also help avoid precision issues that have been showing up from using the highest level (T49179, T49257). This is a pretty simple heuristic that gives ok results. There's more we could do here, such as filtering for vertices/edges adjacent geometric features that need isolation instead of checking them all, but the logic there could get a bit involved. There's potential for slight popping of edges during animation if the dice rate is low, but I don't think this should be a problem since low dice rates really shouldn't be used in animation anyways.

2016-09-15	Revert "Cycles: Tweak empty boundbox children"	Sergey Sharybin
	This reverts commit ecbfa31caaadb03c53c0fe1459718b99613c8804. Original commit broke logic in nodes re-fitting. That area can access non-existing children momentarely. Not sure what would be best solution here, for now simply reverting the change/
2016-09-15	Fix T49179: Parts of mesh disappear with adaptive subdivision	Mai Lavelle
	Problem was zero length normal caused by a precision issue in patch evaluation. This is somewhat of a quick fix, but is better than allowing possible NaNs to occur and cause problems elsewhere.
2016-09-14	Cycles: Deduplicate light pass code	Lukas Stockner

2016-09-14	Cycles: Stop lamp sampling if the lamp isn't visible	Lukas Stockner
	Both spot and area light have large areas where they're not visible. Therefore, this patch stops the light sampling code when one of these cases (outside of the spotlight cone or behind the area light) occurs, before the lamp shader is evaluated. In the case of the area light, the solid angle sampling can also be skipped. In a test scene with Sample All Lights and 18 Area lamps and 9 Spot lamps that all point away from the area that the camera sees, render time drops from 12sec to 5sec.

2016-09-13	Cycles: Implement threaded SVM nodes compilation	Sergey Sharybin
	The title says it all actually. From tests with barber shop scene here gives 2-3x speedup for shader compilation on my oldie i7 machine. The gain is mainly due to textures metadata query from jpeg files (which seems to requite de-compression before metadata can be read). But in theory could give nice improvements for scenes with huge node trees as well (i'm talking about node trees of complexity of fractal which we had reports about in the past).

2016-09-13	Fix T49290: Specific .blend with hair crashes in MacOS 2.78 RC1 on render	Sergey Sharybin
	The issue was caused by some false-positive empty non-AABB intersection. Tried to tweak it a bit so it does not record intersection anymore. Hopefully will work for all platforms. Tested here on iMac and Debian.

2016-09-12	Cycles: Use XDG's .cache folder for cached kernels	Sergey Sharybin
	Basically just moves cached kernels from ~/.config/blender/BLENDER_VERSION to ~/.cache/cycles/kernels. This has following benefits: - Follows XDG specification more closely, not as if it's totally crucial or measurable by users, but still nice. - Prevents unexpected sizes of config folder, makes disk space used in more predictable for users way. - Allows to share kernels across multiple Blender versions, which makes it easier debugging at the times close to release. - "Copy Previous Settings" operator will no longer be copying possibly gigabytes of cached kernels, which used to lead to really nast disk usage and annoying delays of copying settings. - In the future we can have some smart logic to clear old unused cached kernels. Currently only done for Linux and OSX. Windows still follows old "cache" folder logic, but it's not really important for now because we don't support kernel compilation on this platform yet.

2016-09-11	Cycles: Fix shading and crashes resulting from constant folding on displacement	Mai Lavelle
	Constant folding was removing all nodes connected to the displacement output if they evaluated to a constant, causing there to be no valid graph for displacement even when there was displacement to be applied, and sometimes caused crashes.
2016-09-11	Cycles: Replace object index hack with actual checks for SD_TRANSFORM_APPLIED	Mai Lavelle
	Using ones complement for detecting if transform has been applied was confusing and led to several bugs. With this proper checks are made. Also added a few transforms where they were missing, mostly affecting baking and displacement when `P` is used in the shader (previously `P` was in the wrong space for these shaders) Also removed `TIME_INVALID` as this may have resulted in incorrect transforms in some cases.

2016-09-11	Cycles: Fix bump mapping to use object space when used with true displacement	Mai Lavelle
	Bump mapping was happening in world space while displacement happens in object space, causing shading errors when displacement type was used with bump mapping. To fix this the proper transforms are added to bump nodes. This is only done for automatic bump mapping however, to avoid visual changes from other uses of bump mapping. It would be nice to do this for all bump mapping to be consistent but that will have to wait till we can break compatibility.

2016-09-10	Fix OpenSubdiv related buffer overrun with multiple FVar channels.	Alexander Gavrilov
	The existing code uses the input value count of the first channel for all of them. If the first channel is the largest, it leads to a crash-causing buffer overrun in memcpy below. Likely this was left since the time when only one channel was supported. As a crash fix, probably should go into 2.78
2016-09-10	Fix T49303: Fix T49314: More issues with new handling of X11 shortcuts.	Bastien Montagne
	This commits changes two things: * It adds more keysyms preferably taken from XLookupKeysym than XLookupString (namely, all numpad ones). * It falls back to keysyms from XLookupKeysym in other cases, when XLookupString does not produce anything we know of. Finding the correct balance here is far from easy, but think we are comming rather close to it now...

2016-09-09	Cycles: Don't run full shader evaluation for constant emission lamps	Lukas Stockner
	Most of the time, Lamps in Cycles are just a constant emission closure, no texturing etc. Therefore, running a full shader evaluation is wasteful. To avoid that, Cycles now detects these constant emission shaders and stores their value in the lamp data along with a flag in the shader. Then, at runtime, if this flag is set, the lamp code just uses this value and only runs the full shader evaluation if it is neccessary. In scenes with a lot of lamps and with "Sample all direct/indirect" enabled, this saves up to 20% of rendering time in my tests.
