08c1f5bf33 Cycles: Improve sampling of area lights
This patch uses the sampling method described in "A Low Distortion Map Between Triangle and Square" by Eric Heitz.
The benefit is avoiding sqrt in the calculation, which could be cheaper on some architectures, and the result is
more even sampling across the triangle surface.

Based on ideas from

ccf43fe605 Cycles: Fix rendering instanced smoke domain.
The problem was that Cycles would store a pointer to an object in
`DEGObjectIterData->templ_dupli_object`. This pointer was then accessed
when the iterator was already freed.

27cac4a102 Fix T62422: Baking ray distance do not work
The previous naming scheme for the "selected to active" baking options
lead to confusion and they were not describing what they actually did.

To remedy this, I've added a new settings that does what the older setting implied it did.

d9773edaa3 Cycles: code refactor to bake using regular render session and tiles
There should be no user visible change from this, except that tile size
now affects performance. The goal here is to simplify bake denoising in
D3099, letting it reuse more denoising tiles and pass code.

A lot of code is now shared with regular rendering, with the two main
differences being that we read some render result passes from the bake API
when starting to render a tile, and call the bake kernel instead of the
path trace kernel.

With this kind of design where Cycles asks for tiles from the bake API,
it should eventually be easier to reduce memory usage, show tiles as
they are baked, or bake multiple passes at once, though there's still
quite some work needed for that.

c880e54a95 Cycles: Refactor microfacet BSDFs to remove separate anisotropy code
Since the sampling and evaluation functions handle both cases anyways,
there's not really a point for keeping the distinction in the kernel,
so we might as well cut down the number of CLOSURE_BSDF_MICROFACETs a bit.

4cc8123377 UI: Use property split layout and decorators for material properties
Use the automatic property split layout (hence, change to the new 40/60% split
ratio) and add decorator buttons for animatable properties.
This actually applies to all node input buttons in the properties, e.g. world shading,
light shading, texture nodes.

Doing this makes the layout more consistent with other layouts in the
properties. But the decorators are also a useful hint for users that these
options can be animated. Previously using decorators and the automatic split
layout wasn't possible, I've done a number of changes now to have it supported.
Before I moved the socket icons to the left side, the decorators also looked
weird (two circle icons next to each other).

7fc60bff14 UI: Layout changes for new checkbox layout possibilities
Follow-up to previous commit.

Some examples:
{F8473507} {F8473508} {F8473509} {F8473510}
For more screenshots, please see D7430.

We use column or row headings here to bring more structure, and to give
the eye visual anchors which aid eye-scanning. The left-aligned
checkboxes likewise help with this. And we keep the adherence to the
center line, so the alignment matches up between the various buttons and
controls.

* Changes the property split percentage from 50/50% to 40/60%. This is
  needed to give enough space for the checkboxes. But in most cases this
  looks better anyway - see Transform panel. In some cases it simply
  fills out the available space more efficently.
* Fix various hacks where we previously used manually defined splits.
  When we did this, the alignment was never quite right, and the layout
  code was a mess.
* Adds column headings to many places where a list of checkboxes all
  share a common purpose or leading text.
* Add checkbox + value configurations various places where a checkbox
  only serves to enable the value slider
* Removes most uses of grid flow layout. The grid flow layouts combine
  poorly with column headings, and also they would mess alignment up
  badly. The grid flow layouts also often made buttons and controls jump
  around on the screen if you would just resize editors slightly,
  causing visual confusion, making users lose their place. The logic for
  at what time the list of items would re-flow was often flawed, jumping
  to multiple columns too fast or too late - and frankly, the grid flow
  layouts would often just look bad.
