This operator not only links a collection, but it creates a new one and then it
links it. Although the preferrable method for users to handle their collections
is when viewing the "Collections", let's explore this workflow for now.
Suggested by Pablo Vazquez, thank you.
Headers should not have operators as much as possible. The exception here is
for datablocks mode when you want to see the active keyset.
Edit menus on the other hand should be clearly distinct from the RMB context
menus. Edit menu options should be only the ones that apply to the entire
outliner, regardless of the selected element.
Context (rmb) menus should be related to the element you RMB on to invoke the
menu. I'm also taking this opportunity to start bringing the context menus
to Python. There is little reason not to, and it helps editing them (In this
case I'm doing it only for the Scene Collection one).
Using GL_RG16I texture for the hit coordinates increase tremendously the precision of the hit.
The sign of the integer is used to 2 flags (has_hit and is_planar).
We do not store the depth and retrieve it from the depth buffer (increasing bandwith by +8bit/px).
The PDF is stored into another GL_R16F texture.
We remove the raycount for simplicity and to reduce compilation time (less branching in refraction shader).
Brushes themselves are still affected by the mask, but the viewport is not
showing the mask. This way it's easier to see details while sculpting.

For experimental options, outside the scope of typical preferences.
While templates are developed we might want to make changes
to behavior which aren't fully compatible with typical work-flows.
Instead of mixing these options in with current preferences
expose separately (we could even force disable them when templates
aren't int use)
Technically this was introduced in 01b547f993 when
exposing size and randomness for particles.
This "fixes" makes sure particle size and size randomness is always in the
Render panel when it affects the particle system (i.e., always unless using
advanced hair or hair that is not rendering groups/objects).
This allows a duplicator (as known as dupli parent) to be in a visible
collection so its duplicated objects are visible, however while being
invisible for the final render.
An object that is a particle emitter is also considered a duplicator.
Many thanks for the reviewers for the extense feedback.

A comparison should have not just have been against an epsilon,
but relative to the edge length involved.
Thanks to mano-wii for patch on which this is based.
