This was causing the BGE to crash on Debug mode when built with "break on asserts", meaning the BGE was not debuggeable.
Please make sure to test patches in debug mode with the proper flags enabled before committing
This commit:
* Adds a 'compare_ff' function for absolute 'almost equal' comparison of floats.
* Makes 'compare_vxvx' functions use that new 'compare_ff' one.
* Adds a 'compare_ff_relative' function for secured ulp-based relative comparison of floats.
* Adds matching 'compare_vxvx_relative' functions.
* Adds some basic tests for compare_ff_relative.
See https://randomascii.wordpress.com/2012/02/25/comparing-floating-point-numbers-2012-edition/
Note that we could replace our python/mathutils' EXPP_FloatsAreEqual() by BLI's compare_ff_relative
(using a very small absolute max_diff), but these do not have exact same behavior...
Left a comment there for now, we can do it later if/when we are sure it won't break anything!
Enum's itemf callback can be called without context in some cases (UI, doc generation...).
Python's enum properties did not handle this at all - it's kind of odd this did not cause
more trouble and wasn't notice earlier... Probably dynamic enums using context are not
much used in py code.
Note about nodes: those are heavy users of dynamic enum with context. Now,
we expect `NodeCategory.poll()` and `NodeItem.poll()` to always be called with
a valid context (since when there is no context available, we can assume `poll()`
is always True). `NodeCategory.items()`, however, must accept NULL context, so if
you use custom `items` callable for your custom node categories, you may need
to update it (as was done here for builtin `node_group_items()`).
This commit mainly:
* Exposes PreviewImage struct in RNA, including ways for user to set images data.
* Adds a new kind of PreviewImage, using a file path and IMB_thumb to get image.
* Adds a new kind of custom icon using PreviewImage, unrelated to ID previews system.
* Adds a python API (utils.previews) to allow python scripts to access those custom previews/icons.
Note that loading image from files' thumbnails is done when needed (deferred loading), not
when defining the custom preview/icon.
WARNING: for release addons who would want to use this, please keep it to a strict minimum, really needed level.
We do not want our UI to explode under hundreds of different flashy icons!

* There was no real default value for this parameter (neither "" nor None would work the same as
not specifying that parameter). Now, 'None' is considered as default value, and you get
exact same behavior with this value and if not specifying it. This is important at least for
consistency, and potentially too in some esoteric cases (like generated code or so).
* Add a warning about the fact that 'default' parameter shall not be psecified when items
are given a callback function.
Previous text could make think this func was checking whether a point was
inside and on the face, while it actually checks whether the projection
of that point onto the face is inside its boundary...
Adds bpy.app.sdl to expose SDL version information.
When SDL is not available on a Linux system, certain Blender features
are silently disabled (like joystick support in the BGE). This change
is the first step towards making it more obvious why something isn't
working.
SDL information is exposed to Python via bpy.app.sdl, in the same way
as OCIO and OIIO information is exposed.
Generated system-info.txt contains SDL loading method (linked or
dynamically loaded by Blender) and SDL version number.

- all mathutils types
- only works on frozen data (so vectors can be used in sets/dict keys)
- uses same method as CPython, (matches hashing a tuple)
