Add face maps, needed for face-map widgets,
only data structure, widgets will be separate commit.
This comes from 'custom-manipulator' branch with only minor changes.
Yep, that got reported... Was slightly more involved than UI message
fixing though: RNA string length getter shall return exact lentgh of
string (same as strlen), not size of allocated buffer to contain it!
Otherwise, NULL final char leaks in and...
This enables us to use 2D texture arrays for multiple probes.
There is a little artifact with very high roughness caused elongated pixel due to the projection (along every 90° meridian).
DM evaluation code was simply never clearing the `deformedOnly` flag
when evaluating a generative modifier...
Quite astonishing this never got catched before, a lot of particle code
relies on valid value of this flag!!!
We now floor the corner position and use this position as origin.
This gives us perfect derivatives in all cases even if very far from the origin.
Unfortunately this won't fix the low precision of coordinates used for computing the actual grid size, resulting in thick, non-smoothed lines.
Also did a bit of refactor how the axes are drawn.
Do not use the inverse perspective matrix inside the shader to recover world positions.
That leads to severe float imprecision leading to nasty artifacts.
Instead we compute the world view vector for each pixels and do a ray to plane intersection.
We are still getting low precision derivatives when going far away from the origin, and thus artifacts.
This commit also fixes the non-appearing negative Z axis in 3D view.
The fact that we can end with uninstantiated objects is not expected
currently, but would rather not start chasing all corner cases that may
lead to that situation.
User shall be able to delete uninstantiated objects from Outliner, though!
Properly remap nodes' pointers to copied IDs in copied ntrees.
Note that this only affects root trees, node groups are not concerned
here, since they are assumed to be reusable chunks and hence *not*
duplicated.
The operator is indeed not adding frames but inserting them at the current frame (shifting all subsequent ones). Changed the operator name and description.
Approved by Antonio.
The Issue
=======
For a long time now MinGW has been unsupported and unmaintained and at this point,
it looks like something that we should just leave behind and move on.
Why Remove
==========
One of the big motivations for MinGW back in the day is that it was free compared to MSVC which was licensed based.
However, now that this is no longer true we have basically stopped updating the need CMake files.
Along with the CMake files, there are several patches to the extern libs needed to make this work. For example, see:
https://developer.blender.org/diffusion/B/browse/master/extern/carve/patches/mingw_w64.patch
If we wanted to keep MinGW then we would need to make more custom patches to the external libs and
this is not something our platform maintainers are willing to do.
For example, here is the patches needed to build python: https://github.com/Alexpux/MINGW-packages/tree/master/mingw-w64-python3
Fixes T51301

We had handling of fully duplicated polygons already, but... absolutely
nothing to sanitize partially merged polygons! This were giving us
totally invalid geometry, with duplicated vertices in single poly,
invalid edges, etc.
Now we do check for invalid loops inside polys, and generate new edges
as needed to get only valid polys.
For some reason this was a nightmare to get running fully OK, playing
with old and new indices is really, really mind breaking.
Note for users
==============
The active_layer option used for the filebrowser operators is now called
active_collection.
If there is no collections in the scenelayer or if this option is not selected
we automatically create a new collection for the new objects.
This is the same behaviour of trying to add a new object when there is
no collection.
Note for developers
===================
For those cases I moved the object user count handling from readfile to
the scene collection system. It's working fine for those, but we still
need to re-visit this for Add objects, and Duplicate - In those cases
the usercount is 2 when it should be 1.
