Practically all access to enum data is read-only.

2.8x branch added bContext arg in many places,
pass eval-context instead since its not simple to reason about what
what nested functions do when they can access and change almost anything.
Also use const to prevent unexpected modifications.
This fixes crash loading files with shadows,
since off-screen buffers use a NULL context for rendering.
|
|
Note that some little parts of code have been dissabled because eval_ctx
was not available there. This should be resolved once DerivedMesh is
replaced.

BKE_depsgraph.h
This removes BKE_depsgraph.h and depsgraph.c

Intended to replace legacy GL_SELECT, without the limitations of
sample queries which can't access depth information.
This commit adds VIEW3D_SELECT_PICK_NEAREST and VIEW3D_SELECT_PICK_ALL
which access the depth buffers to detect whats under the pointer,
so initial selection is always the closest item.
The performance of this method depends a lot on the OpenGL
implementations glReadPixels.
Since reading depth can be slow, buffers are cached for object picking
so selecting re-uses depth data, performing 1 draw instead of 3
(for 24, 18, 10 px regions, picking with many items under the pointer).
Occlusion queries draw twice when picking nearest,
so worst case 6x draw calls per selection.
Even with these improvements occlusion queries is faster on AMD hardware.
Depth selection is disabled by default, toggle option under select method.
May enable by default if this works well on different hardware.

Increment the seed on each use,
otherwise calling again selects the same order, unless you manually adjust the seed.

While SCons building system was serving us really good for ages it's no longer
having much attention by the developers and started to become quite a difficult
task to maintain.
What's even worse -- there started to be quite serious divergence between SCons
and CMake which was only accumulating over the releases now. The fact that none
of the active developers are really using SCons and that our main studio is also
using CMake spotting bugs in the SCons builds became quite a difficult task and
we aren't always spotting them in time.
Meanwhile CMake became really mature building system which is available on every
platform we support and arguably it's also easier and more robust to use.
This commit includes:
- Removal of actual SCons building system
- Removal of SCons git submodule
- Removal of documentation which is stored in the sources and covers SCons
- Tweaks to the buildbot master to stop using SCons submodule
(this change requires deploying to the server)
- Tweaks to the install dependencies script to skip installing or mentioning
SCons building system
- Tweaks to various helper scripts to avoid mention of SCons folders/files
as well

Meta-balls would access freed memory on undo.
This fixes the bug and stores the active-meta in the undo state.

- use ED_ prefix for api calls
- use ED_*_select_pick for mouse selection (was already done in parts)

Add 'Seed' option for all random select operators

Our 'hard limit' values was too often max_int/float here, mis-typing could
lead to crash (or infinite hanging) of Blender, see e.g.

Naming here is slightly misleading. We have:
* Number of elements (objects) that can be picked
* Buffer size
* Number of integers in buffer.
Interestingly enough, bufsize in OpenGL (as far as I could find in
examples on the web) and in most of the code refers to the latter and
actual buffer size is only used whenever we do allocations on the heap.
Added an extra defines here to make things a bit clearer:
* MAXPICKELEMS refers to the number of objects that can be picked
* MAXPICKBUF refers to the number of integers in the selection buffer
Also made all buffers use MAXPICKBUF where some used MAXPICKBUF * 4.
That means that some parts of blender will use less space for selection
now. MAXPICKBUF is set to 10000 for 2500 object selection, which can be
changed at any time, but I think 10000 integers on the stack touches the
borders of uglyland anyway.

This patch creates an interface for selection mechanisms in opengl. This
makes it possible to switch between occlusion query based or select
rendermode based selection transparently.
This is really useful on graphics drivers that do not accelerate the
select rendermode path (some ATI cards are notorious for this, and the
new path is used by default there), since occlusion queries are always
hardware accelerated due to their use in games.
The option can be found under system - selection. Auto just enables
occlusion queries for ATI users while the rest of the options enforce
one of the two methods always.
There is just one known change, previous code enforced nearest bone to
always get selected, even when mouse selecting near the same position, I
couldn't replicate the behaviour though.
patch by me with edits and review by Campbell.
Thanks!

curves and metaballs now behave the same as meshes wrt grid scaling.
remove WM_operator_view3d_distance_invoke(), and replace with a function called from exec which initializes defaults, this way operators can have their own invoke functions.

takes a key as an arg and isnt popping any element from the hash as you might expect).
add BLI_pophead/tail, since getting the first element from a list and removing it is a common task.

hangs Blender
Wiresize and rendersize were not handled regarding scene scale, leading to insane precision when working in cm or less...

Forward enum declaration is a bad idea, especially for C++ which requires
enum specification to dteermine which data type to use to store it.
Alternative would be to not use enum as an arument and pass it as int,
but actually would rather be strict on typing -- using explicit enum
as parameter type helps understanding the code and prevents possible
mistakes when using the function.

generator with a local one. It's not thread safe and will not give repeatable
results, so in most cases it should not be used.
Also fixes #34992 where the noise texture of a displacement modifier was not
properly random in opengl animation render, because the seed got reset to a
fixed value by an unrelated function while for final render it changed each
frame.

ShrinkFatten operator now uses scale key to toggle 'Even thickness' option.
With the default keymap this is Alt+S,S.
Added functionality so the header print can get the key used for the modal keymap, some other operators should make use of this too.

Made it so meshes, curves, surfaces and metaballs are scaling to a grid cell size,
which makes them behave consistently now.
There're still issues to be resolved still:
- Lattice is not scaled to grid cell size yet, it uses slightly different add
function which makes scaling a bit tricky and hacky. Would prefer to do a
bit bigger refactor here, so it's a TODO for now.
- Cameras, speakers and other helpers are not scaling. They don't have data
on which scale could be applied and perhaps it should be some kind of draw
scale. Also would consider it's a TODO for now.
