Dynamically sized regions in the topbar were flickering due to only updating
their size after redraws. Now there is an optional layout() callback for
all regions in an area to do UI layout first, then refresh the region layout,
and then do the actual drawing for each region.
Task T54753
Note: Quad-View region overlay drawing is not working because of e01cadd657.
However I tested this patch after reverting that commit locally and this
patch's code seems fine.
Partial revert of 3d62230ed6.
For Blender 2.8 we had to be compatible with very old OpenGL versions, and
triple buffer was designed to work without offscreen rendering, by copying
the the backbuffer to a texture right before swapping. This way we could
avoid redrawing unchanged regions by copying them from this texture on the
next redraws. Triple buffer used to suffer from poor performance and driver
bugs on specific cards, so alternative draw methods remained available.
Now that we require newer OpenGL, we can have just a single draw method
that draw each region into an offscreen buffer, and then draws those to
the screen. This has some advantages:
* Poor 3D view performance when using Region Overlap should be solved now,
since we can also cache overlapping regions in offscreen buffers.
* Page flip, anaglyph and interlace stereo drawing can be a little faster
by avoiding a copy to an intermediate texture.
* The new 3D view drawing already writes to an offscreen buffer, which we
can draw from directly instead of duplicating it to another buffer.
* Eventually we will be able to remove depth and stencil buffers from the
window and save memory, though at the moment there are still some tools
using it so it's not possible yet.
* This also fixes a bug with Eevee sampling not progressing with stereo
drawing in the 3D viewport.

The only real reason we need `butspacetype` is while switching areas, where we
need to delay the actual switch to the RNA _update callback since only there we
can access context.
So instead of trying to sync it with `spacetype`, only set while needed and
unset it afterwards (as in set to `SPACE_EMPTY`).
This should also allow us to re-use `butspacetype` in versioning code when
trying to read removed editors. It'll store the space type value of the removed
editor which we can then use on versioning.
For backwards compatibility, we store `butspacetype` with the value of
`spacetype`.
This makes easier to distinguish between different editors
(as oppose to an editor and its regions).
Note action zones look a bit strange with this. I recommend we do next:
* Make sure all 4 corners can be used as action zones.
* Remove their drawing code (or show them only on mouse hover).
Requiring context means we can't easily create new editors to replace deprecated
ones in versioning code.
Think it's reasonable to give editors access to scene and area data for their
initial setup though. They mostly need it for setting "the view", as in,
scrolling values.
Also did minor cleanup in top-bar creation function.
* Make bottom half of topbar a bit higher
* Make tabs higher and put them closer together
* Remove screen layouts dropdown, we'll have one layout per window
* Hide action zones from topbar
* Don't change topbar background color when activating
This commit removes all references to the old timeline editor.
Unfortuantely, the removal of the Timeline spacetype defining
functions has ended up breaking the version patching code I'd
been working on earlier (as now, the editor gets marked as
"unknown/info" before we get a chance to patch it!)
== Main Features/Changes for Users
* Add horizontal bar at top of all non-temp windows, consisting out of two horizontal sub-bars.
* Upper sub-bar contains global menus (File, Render, etc.), tabs for workspaces and scene selector.
* Lower sub-bar contains object mode selector, screen-layout and render-layer selector. Later operator and/or tool settings will be placed here.
* Individual sections of the topbar are individually scrollable.
* Workspace tabs can be double- or ctrl-clicked for renaming and contain 'x' icon for deleting.
* Top-bar should scale nicely with DPI.
* The lower half of the top-bar can be hided by dragging the lower top-bar edge up. Better hiding options are planned (e.g. hide in fullscreen modes).
* Info editors at the top of the window and using the full window width with be replaced by the top-bar.
* In fullscreen modes, no more info editor is added on top, the top-bar replaces it.
== Technical Features/Changes
* Adds initial support for global areas
A global area is part of the window, not part of the regular screen-layout.
I've added a macro iterator to iterate over both, global and screen-layout level areas. When iterating over areas, from now on developers should always consider if they have to include global areas.
* Adds a TOPBAR editor type
The editor type is hidden in the UI editor type menu.
* Adds a variation of the ID template to display IDs as tab buttons (template_ID_tabs in BPY)
* Does various changes to RNA button creation code to improve their appearance in the horizontal top-bar.
* Adds support for dynamically sized regions. That is, regions that scale automatically to the layout bounds.
The code for this is currently a big hack (it's based on drawing the UI multiple times). This should definitely be improved.
* Adds a template for displaying operator properties optimized for the top-bar. This will probably change a lot still and is in fact disabled in code.
Since the final top-bar design depends a lot on other 2.8 designs (mainly tool-system and workspaces), we decided to not show the operator or tool settings in the top-bar for now. That means most of the lower sub-bar is empty for the time being.
NOTE: Top-bar or global area data is not written to files or SDNA. They are simply added to the window when opening Blender or reading a file. This allows us doing changes to the top-bar without having to care for compatibility.
== ToDo's
It's a bit hard to predict all the ToDo's here are the known main ones:
* Add options for the new active-tool system and for operator redo to the topbar.
* Automatically hide the top-bar in fullscreen modes.
* General visual polish.
* Top-bar drag & drop support (WIP in temp-tab_drag_drop).
* Improve dynamic regions (should also fix some layout glitches).
* Make internal terminology consistent.
* Enable topbar file writing once design is more advanced.
* Address TODO's and XXX's in code :)
Thanks @brecht for the review! And @sergey for the complaining ;)

ViewRender was removed, which means we can't get the render engine for files
saved in 2.8. We assume that any files saved in 2.8 were intended to use Eevee
and set the engine to that.
A fix included with this is that .blend thumbails now draw with Clay mode,
and never Eevee or Cycles. These were drawn with solid mode in 2.7, and should
be very fast and not e.g. load heavy image textures.

Folders removed entirely:
* //extern/recastnavigation
* //intern/decklink
* //intern/moto
* //source/blender/editors/space_logic
* //source/blenderplayer
* //source/gameengine
This includes DNA data and any reference to the BGE code in Blender itself.
We are bumping the subversion.
Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.
This adds initial multi-object editing support.
- Selected objects are used when entering edit & pose modes.
- Selection & tools work on all objects however many tools need porting
See: T54641 for remaining tasks.
Indentation will be done separately.
See patch: D3101
- Wasn't clear which functions handle edit-bones.
- Mixed both ebone and edit_bone in names.
- Didn't use ED_armature_* prefix for public API.
See P655 to apply to branches.
Fixes the "emtpy scrolling" glitch by clamping the scroller offset to
the boundary of the view when it's smaller than the previous.
Fixes T45197. Patch by @januz.
Differential Revision: D1580
- Metadata handling is now separate from `ImBuf *`, allowing it to be
used with a generic `IDProperty *`.
- Merged `IMB_metadata_add_field()` and `IMB_metadata_change_field()`
into a more robust `IMB_metadata_set_field()`. This new function
doesn't return any status (it now always succeeds, and the previously
existing return value was never checked anyway).
- Removed `IMB_metadata_del_field()` as it was never actually used
anywhere.
- Use `IMB_metadata_ensure()` instead of having
`IMB_metadata_set_field()` create the containing `IDProperty` for
you.
- Deduplicated function declarations, moved `intern/IMB_metadata.h` out
of `intern/`. Note that this does mean that we have some extra
`#include "IMB_metadata.h"` lines now, as the metadata functions are
no longer declared in `IMB_imbuf.h`.
- Deduplicated function declarations, all metadata-related declarations
are now in imbuf/IMB_metadata.h.
