	No functional changes
2020-08-07	Code Style: use "#pragma once" in source directory	Jacques Lucke
	This replaces header include guards with `#pragma once`. A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`), because they are used in other places. This patch has been generated by P1561 followed by `make format`. Differential Revision: https://developer.blender.org/D8466
2020-03-19	Cleanup: `make format` after SortedIncludes change	Dalai Felinto

2019-04-17	ClangFormat: apply to source, most of intern	Campbell Barton
	Apply clang format as proposed in T53211. For details on usage and instructions for migrating branches without conflicts, see: https://wiki.blender.org/wiki/Tools/ClangFormat
2019-02-18	Cleanup: conform headers to have license first	Campbell Barton
	Also remove doxy comments for licenses and add missing GPL header.
2019-02-01	Cleanup: remove redundant, invalid info from headers	Campbell Barton
	BF-admins agree to remove header information that isn't useful, to reduce noise. - BEGIN/END license blocks Developers should add non license comments as separate comment blocks. No need for separator text. - Contributors This is often invalid, outdated or misleading especially when splitting files. It's more useful to git-blame to find out who has developed the code. See P901 for script to perform these edits.

2015-08-27	Fix T45617: Map UV node produces image artifacts	Sergey Sharybin
	Basically filtering was happening twice, first time by applying weights of EWA filter itself and then by applying subpixel offset while reading pixel values.
2015-01-19	D627: Memory usage optimization for the compositor.	Jeroen Bakker
	The compostor used a fixed size of 4 floats to hold pixel data. this patch will select size of a pixel based on its type. It uses 1 float for Value, 3 float for vector and 4 floats for color data types. When benchmarking on shots (opening shot of caminandes) we get a reduction of memory of 30% and a tiny speedup as less data transformations needs to take place (but these are negligable. More information of the patch can be found on https://developer.blender.org/D627 and http://wiki.blender.org/index.php/Dev:Ref/Proposals/Compositor2014_p1.1_TD Developers: jbakker & mdewanchand Thanks for Sergey for his indept review.
2014-04-15	Structural cleanup and improvements for the compositor.	Lukas Tönne
	Many parts of the compositor are unnecessarily complicated. This patch aims at reducing the complexity of writing nodes and making the code more transparent. == Separating Nodes and Operations == Currently these are both mixed in the same graph, even though they have very different purposes and are used at distinct stages in the compositing process. The patch introduces dedicated graph classes for nodes and for operations. This removes the need for a lot of special case checks (isOperation etc.) and explicit type casts. It simplifies the code since it becomes clear at every stage what type of node we are dealing with. The compiler can use static typing to avoid common bugs from mixing up these types and fewer runtime sanity checks are needed. == Simplified Node Conversion == Converting nodes to operations was previously based on "relinking", i.e. nodes would start with by mirroring links in the Blender DNA node trees, then add operations and redirect these links to them. This was very hard to follow in many cases and required a lot of attention to avoid invalid states. Now there is a helper class called the NodeConverter, which is passed to nodes and implements a much simpler API for this process. Nodes can add operations and explicit connections as before, but defining "external" links to the inputs/outputs of the original node now uses mapping instead of directly modifying link data. Input data (node graph) and result (operations graph) are cleanly separated. == Removed Redundant Data Structures == A few redundant data structures have been removed, notably the SocketConnection. These are only needed temporarily during graph construction. For executing the compositor operations it is perfectly sufficient to store only the direct input link pointers. A common pointer indirection is avoided this way (which might also give a little performance improvement). == Avoid virtual recursive functions == Recursive virtual functions are evil. They are very hard to follow during debugging. At least in the parts this patch is concerned with these functions have been replaced by a non-virtual recursive core function (which might then call virtual non-recursive functions if needed). See for example NodeOperationBuilder::group_operations.
2013-12-04	Fix for EWA (elliptical weighted average) sampling in the compositor.	Lukas Tönne
	EWA sampling is designed for downsampling images, i.e. scaling down the size of input image pixels, which happens regularly in compositing. While the standard sampling methods (linear, cubic) work reasonably well for linear transformations, they don't yield good results in non-linear cases like perspective projection or arbitrary displacement. EWA sampling is comparable to mipmapping, but avoids problems with discontinuities. To work correctly the EWA algorithm needs partial derivatives of the mapping functions which convert output pixel coordinates back into the input image space (2x2 Jacobian matrix). With these derivatives the EWA algorithm projects ellipses into the input space and accumulates colors over their area. This calculation was not done correctly in the compositor, only the derivatives du/dx and dv/dy were calculation, basically this means it only worked for non-rotated input images. The patch introduces full derivative calculations du/dx, du/dy, dv/dx, dv/dy for the 3 nodes which use EWA sampling currently: PlaneTrackWarp, MapUV and Displace. In addition the calculation of ellipsis area and axis-aligned bounding boxes has been fixed. For the MapUV and Displace nodes the derivatives have to be estimated by evaluating the UV/displacement inputs with 1-pixel offsets, which can still have problems on discontinuities and sub-pixel variations. These potential problems can only be alleviated by more radical design changes in the compositor functions, which are out of scope for now. Basically the values passed to the UV/Displacement inputs would need to be associated with their 1st order derivatives, which requires a general approach to derivatives in all nodes.
2013-11-19	Cleanup: Renamed compositor executePixel functions and their 'read' wrappers ↵	Lukas Tönne
	in SocketReader. Distinguish the 3 different methods for acquiring pixel color values (executePixel, executePixelSampled, executePixelFiltered). This makes it easier to keep track of the different sampling methods (and works nicer with IDEs that do code parsing). Differential Revision: http://developer.blender.org/D7
2013-09-05	Fix #36113, Translate's wrapping has 1 pixel gap in X and Y after scale node.	Lukas Toenne
	The issue with wrapping is that it requires correct interpolation of the border pixels. Since interpolation is done at the far left end of the node tree in buffer/image/etc read operations, the wrapping setting can not be used directly in those operations (otherwise in-line translate operations would cause conflicts). To make wrapping work correctly we need to add a buffer in front of the translate operation, which can then be interpolated correctly based on wrapping. The WrapOperation becomes a variant of ReadBufferOperation, which uses its wrapping setting to determine the correct "extend" mode for interpolation of the buffer.
2013-09-05	Extend mode option for MemoryBuffer reading in compositor. This will allow ↵	Lukas Toenne
	proper interpolation of pixel values when using wrapping in the Translate node. Implemented in inline functions, so won't cause overhead if constant values are passed (as happens with most calls using the default argument).
2013-08-16	Fix for #36468, "Buffer Groups" option changes compositing output.	Lukas Toenne
	Problem is that the read/write buffer operations only work with actual image inputs. If a singular value is used as group input no actual buffer will be created, the write operation does not schedule any chunks and the ReadBufferOperation subsequently returns zero (MemoryBuffer::read). The fix uses the (0,0) resolution to detect single value input of the WriteBufferOperation. The actual resolution is then clamped to (1,1) to ensure we have a single pixel to store the value in. A m_single_value flag is also set, so we can reliably distinguish this from genuine image resolutions without having to check m_width/m_height later on. The ReadBufferOperation copies this flag from the associated WriteBufferOperation and if set will always return the single value from pixel (0,0).
2012-08-16	compositor - EWA filter was blurring too much by default, this caused the ↵	Campbell Barton
	displace node to blur the image when no displacement was applied, making images fuzzy, the original C code has an interpolation option. Added this option back and use for displace and UV composite nodes.
