Previously the playback mode "Frame Dropping" would not drop the correct
number of frames which would lead to slow playback.
For example, the playback target is 60fps. However we can only muster
around 32 fps.
The delta frames from the last step is in this case ~1.98 or so.
With the previous code, we would floor this. That would lead us to step
forward one frame each time, effectively playing back the animation at
half the speed as we will try to render every frame.
To fix this we simply save the remaining fraction from the previous
frame and use it to compute the current frame step.

This was because of the use of uninitialized buffers for TAA.
This patch is a quick fix for the issue which is a missing tagging for a
complete viewport update.
- Changing API for time values from float to double for better precision.
- Fixing minor mistakes in the documentation.
- Fixing minor unnecessary large memory allocation.
The problem comes from the fact by no data being modified when switching
viewlayers.
To follow what the external render engines do, we completely reset the
viewport by freeing the GPUViewport to avoid any cached data from being
kept.
Although we still dynamically hide scrollbars, they don't change the
region size anymore. They are simply drawn on top of the region content.
Because of this, some hacks introduced by fa28e50ac2 are no longer
necessary.
Without these hacks, the scrollbar visibility is evaluated much more
often (cheap operation) which should be more reliable and possibly solve
some glitches.
Also replaces integers passed as booleans.
Fixes T75782.
Note this only changes cases where the variable was declared inside
the for loop. To handle it outside as well is a different challenge.

Follow up of b2ee1770d4 and 10c2254d41, part of T74432.
Now the area and region naming conventions should be less confusing.
Mostly a careful batch rename but had to do few smaller fixes.
Also ran clang-format on affected files.
Both the MS headers and blender headers define the HKEY
which gives all kind of inclusion order issues.
This diff renames all *KEY constants to EVT_*KEY to resolve
this conflict.

NOTE: While most of the milestone 1 goals are there, a few smaller features and
improvements are still to be done.
Big picture of this milestone: Initial, OpenXR-based virtual reality support
for users and foundation for advanced use cases.
Maniphest Task: https://developer.blender.org/T71347
The tasks contains more information about this milestone.
To be clear: This is not a feature rich VR implementation, it's focused on the
initial scene inspection use case. We intentionally focused on that, further
features like controller support are part of the next milestone.
- How to use?
Instructions on how to use this are here:
https://wiki.blender.org/wiki/User:Severin/GSoC-2019/How_to_Test
These will be updated and moved to a more official place (likely the manual) soon.
Currently Windows Mixed Reality and Oculus devices are usable. Valve/HTC
headsets don't support the OpenXR standard yet and hence, do not work with this
implementation.
---------------
This is the C-side implementation of the features added for initial VR
support as per milestone 1. A "VR Scene Inspection" Add-on will be
committed separately, to expose the VR functionality in the UI. It also
adds some further features for milestone 1, namely a landmarking system
(stored view locations in the VR space)
Main additions/features:
* Support for rendering viewports to an HMD, with good performance.
* Option to sync the VR view perspective with a fully interactive,
regular 3D View (VR-Mirror).
* Option to disable positional tracking. Keeps the current position (calculated
based on the VR eye center pose) when enabled while a VR session is running.
* Some regular viewport settings for the VR view
* RNA/Python-API to query and set VR session state information.
* WM-XR: Layer tying Ghost-XR to the Blender specific APIs/data
* wmSurface API: drawable, non-window container (manages Ghost-OpenGL and GPU
context)
* DNA/RNA for management of VR session settings
* `--debug-xr` and `--debug-xr-time` commandline options
* Utility batch & config file for using the Oculus runtime on Windows.
* Most VR data is runtime only. The exception is user settings which are saved
to files (`XrSessionSettings`).
* VR support can be disabled through the `WITH_XR_OPENXR` compiler flag.

A few thank you's:
* A huge shoutout to Ray Molenkamp for his help during the project - it would
have not been that successful without him!
* Sebastian Koenig and Simeon Conzendorf for testing and feedback!
* The reviewers, especially Brecht Van Lommel!
* Dalai Felinto for pushing and managing me to get this done ;)
* The OpenXR working group for providing an open standard. I think we're the
first bigger application to adopt OpenXR. Congratulations to them and
ourselves :)
This project started as a Google Summer of Code 2019 project - "Core Support of
Virtual Reality Headsets through OpenXR" (see

Steps to reproduce were:
* Disable tool settings region in 3D View (View > Tool Settings)
* Split the 3D View and drag all the way down
The removed code doesn't seem to be needed anymore. Tested this on hiDPI
too, seems fine.
These kind of fixes are always tricky, so I wouldn't be surprised if
there are any issues caused by this.
This commit is a full refactor of the grease pencil modules including Draw Engine, Modifiers, VFX, depsgraph update, improvements in operators and conversion of Sculpt and Weight paint tools to real brushes.
Also, a huge code cleanup has been done at all levels.
Thanks to @fclem for his work and yo @pepeland and @mendio for the testing and help in the development.

While it might be handy to have type-less functionality which is
similar to how C++ math is implemented it can not be easily achieved
with just preprocessor in a way which does not have side-effects on
wrong usage.
There macros where often used on a non-trivial expression, and there
was at least one usage where it was causing an actual side effect/bug
on Windows (see change around square_f(sh[index++]) in studiolight.c).
For such cases it is handy to have a function which is guaranteed to
have zero side-effects. The motivation behind actually removing the
macros is that there is already a way to do similar calculation. Also,
not having such macros is a way to guarantee that its usage is not
changed in a way which have side-effects and that it's not used as an
inspiration for cases where it should not be used.

The old convention was easy to confuse with ScrArea.
Part of https://developer.blender.org/T74432.
This is mostly a batch rename with some manual fixing. Only single word
variable names are changed, no prefixed/suffixed names.
Brecht van Lommel and Campbell Barton both gave me a green light for
this convention change.
Also ran clan clang format on affected files.
Part of https://developer.blender.org/T74429.
There's a chance that this causes some issues becaue in some cases we
change from getting the window from context to getting it from somewhere
else.
- Move gizmo cursor check into ED_region_cursor_set so the result of
calling this function is the same as flagging for cursor update.
- Use tagging in ui_popup_block_remove which avoids adding a
mouse-move event in case the cursor needs to be changed again.
