2020-03-09GPencil: Refactor of Draw Engine, Vertex Paint and all internal functionsAntonio Vazquez
This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes. Also, a huge code cleanup has been done at all levels. Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.

2020-03-09Cleanup: Replace ABS/SQUARE/CUBE with function callsSergey Sharybin
While it might be handy to have type-less functionality which is similar to how C++ math is implemented it can not be easily achieved with just preprocessor in a way which does not have side-effects on wrong usage. There macros where often used on a non-trivial expression, and there was at least one usage where it was causing an actual side effect/bug on Windows (see change around square_f(sh[index++]) in studiolight.c). For such cases it is handy to have a function which is guaranteed to have zero side-effects. The motivation behind actually removing the macros is that there is already a way to do similar calculation. Also, not having such macros is a way to guarantee that its usage is not changed in a way which have side-effects and that it's not used as an inspiration for cases where it should not be used.

2020-03-06Fix integer overflow in BLI_mempool_as_arrayN()Sergey Sharybin
`(size_t)(int * int)` will actually cast overflown integer to size_t, which isn't what was intended here. Correct thing would be to cast in the following manner `(size_t)int * int`. In this particular case can as well use function which is designed to allocate an array of memory without overflow.
2020-03-06Cleanup: use ELEM macro for path slash checksCampbell Barton
2020-03-06Cleanup: avoid use of BLI_cleanup_dirCampbell Barton
Some cases don't need to add the trailing slash. Use BLI_cleanup_path in this case.
2020-03-06Cleanup: remove BLI_cleanup_fileCampbell Barton
In practice, references to files rarely have trailing slashes (by accident). Remove this function in favor of BLI_cleanup_path.

2020-03-04Cleanup: remove unused BLI_strncat_utf8Campbell Barton
Behaves differently to strncat, BLI_strncpy_utf8_rlen can be used for a similar purpose.

Utility to join strings into a fixed size buffer.
2020-03-04BLI_math: inline clamp functionsCampbell Barton
These are used in some per-pixel operations such as image sampling and color conversion, where replacing existing macro use could add overhead.

2020-03-03Fix delaunay triangulation, bad indices for output faces.Howard Trickey
If there were merged vertices, sometimes the output faces had wrong vertex indices. Added a test for this, and fixed.

2020-03-02Fix T65568: sewing and self collision issueIsh Bosamiya
As explained in T65568 by @LucaRood, the self collision system should exclude triangles that are connected by sewing springs. Differential Revision: https://developer.blender.org/D6911
2020-03-01Fix problem with Delaunay triangulalation re output mapping.Howard Trickey
The array giving original vertex indices should not contain entries for newly created vertices. Added a test to check this.
2020-02-29Made BLI_delaunay_2d_cdt_calc better at tiny feature elimination.Howard Trickey
The 'random' unit tests and some examples from the new boolean code triggered asserts and crashes. This fixes those. There is a new flag in the input that optionally disables a pass over input to snap segment edges to other segments.

This isn't needed with modern compilers.
2020-02-19BLI_math: unify zero area checks for barycentric weight calculationCampbell Barton
This applies the change from T73348 fix to related functions. Instead of checking against an epsilon to avoid divide by zero, perform the division and check the result is finite. This is needed since small faces can have an area under 'FLT_EPSILON', and dividing by values close to zero can result in 'inf'.
2020-02-18Fix making paths relative on windowsCampbell Barton
Comparing the drive letter was case sensitive, causing 'BLI_path_rel' to fail in common cases (manually entering a lower case drive letter for example). Surprisingly this issue dates back to 2005 and wasn't reported.
2020-02-17ColorManagement: Dithering ImprovementClément Foucault
- Unlock property range. - Use triangular noise to keep perceptual noise error more uniform. Remap range to preserve perceptual intensity. - Center noise distribution around 0 for GPU implementation because of rounding. - Do dithering after merging overlays. Effect of using triangular noise is not really noticeable if you don't use really low bitdepth. But doing a test in the shader were we artificially reduce the bitdepth (`col = (col * 16) / 16;`) reveals the real difference.

2020-02-15Modifiers: Add option to directly specify a 2D transform for UVWarpLukas Stockner
Currently the only option is to warp based on the transform of other objects, which is inconvenient if you want to e.g. control it through a driver - you need to set up a dummy object and go through that, which is clunky and should be unneccessary.

2020-02-11Sculpt: Split normal radius and area radiusPablo Dobarro
This enables an extra layer of control in the sculpt brushes. For now it is enabled only in Scrape, but it should work in all brushes (like normal radius). In the future it may also be enabled in other brushes. You can tweak in this property in the scrape brush to achieve a much better behavior when working on curve surfaces and control how much volume you want to trim. In most cases, it also fixes the bug where the brush keeps trimming in the same area without disabling accumulate. It should be possible to fix some other artifacts in other brushes by tweaking this default property. Reviewed By: jbakker Differential Revision: https://developer.blender.org/D5993

The changes come from the `functions` branch, where I'm using these structures a lot. This also includes a new `BLI::Optional<T>` type, which is similar to `std::Optional<T>` which can be used when Blender starts using C++17.
