This changes BKE's fitting code to use `BKE_camera_params_compute_viewplane` instead of
`BKE_camera_view_frame`. This allows that code to work with orthographic projection too.
Also, two funcs were added to rna's Object, to resp. get the projection matrix of that
object (mostly useful for cameras and lamps objects), and return position this object
should be to see all (to fit) a given set of points.

Differential Revision: https://developer.blender.org/D961
The ones in extern/glew-es have been changed to NOTE instead of XXX
GHOST_ContextEGL.cpp: It really does seem that it is not possible to query the swap interval using EGL
GHOST_WidnowCocoa.h: The comment referring to Carbon is clearly out of date, so I removed it.
math_geom.c: The node about not using tmax again is correct, but the code is kept for a future maintainer who will need to know how to compute it if they modify that code.
paint_image_proj.c (2698): The question about integer truncation does not appear to have been resolved. It still seems to be an incorrectly implementation of rounding (I'd suggest using the round function instead of this hack).
This was a ToDo item, for mesh-based rigid body shapes (trimesh, convex)
the operator was simply using the bounding box volume, which can grossly
overestimate the volume and mass.
Calculating the actual volume of a mesh is not so difficult after all,
see e.g.
http://research.microsoft.com/en-us/um/people/chazhang/publications/icip01_ChaZhang.pdf
This patch also allows calculating the center-of-mass in the same way.
This is currently unused, because the rigid body system assumes the CoM
to be the same as the geometric object center. This is fine most of the
time, adding such user settings for "center-of-mass offset" would also
add quite a bit of complexity in user space, but it could be necessary
at some point. A number of other physical properties could be calculated
using the same principle, e.g. the moment of inertia.
Compute barycentric coordinates (u, v) for a point with respect to a
triangle.
This is needed for Cycles baking but we decided to push this
independently of the upcoming main baking changes.
Code adapted from Christer Ericson's Real-Time Collision Detection.
Cleanup, refactoring and review from Campbell Barton.
Issue was in BLI's rotation_between_vecs_to_quat(), which did not handled correctly cases where both vectors are colinear.
Patch by Campbell Barton and me.
Issue originaly tracked down by Yan Shi, many thanks!
