Fix mistake in angular spring generation

crash fix for particle grid emission, do not allow to re-distribute particles there...

Remove "Use Global Scene" option

This option isn't really needed now that scenes are only on window level.

Remove redundant Depsgraph update call

Scene can't be changed by changing a screen or workspace anymore.

Show 'Manipulate Center Points' in weight paint mode

If the active object is in weight paint mode, but some armatures in pose mode, 'manipulate center points' still affects the transformation. See bd2034a749a9a9.

Also removed redundant check, we basically did the same check for paint modes twice.

Make object mode part of the workspace

Each workspace now stores the last set object mode type, activating a workspace also activates this mode. This commit also removes the object mode menu from the 3D view header, it's displayed in the info editor header now (and later will be in the top-bar).

We have one issue with Grease Pencil here though: The active grease pencil data-block depends on the active editor, and an editor can only enter GPencil edit mode if it has an active GPencil data-block. The new object mode menu is independent of 3D Views (or any other editor supporting GPencil) though. For now the menu simply won't show the GPencil edit mode item, it will be back once GPencil gets its own object type (as planned). GPencil still provides other ways to enter this mode.

Dynamic Paint: Fix random pixel flooding by absolute brush with spread.

If a very low wetness absolute alpha brush is used with spread and
drying effects enabled, some pixels will rapidly accumulate paint.
This happens because paint drying code applies a minimal wetness
threshold that causes the paint to instantly dry out.

Specifically, every frame the brush adds paint at the specified
absolute alpha and wetness set to the minimal threshold, spread
drops it below threshold, and finally drying moves all paint to
the dry layer. This drastically accelerates the rate of flow of
paint into the affected pixels.

Fortunately, the reason paint spread actually ends up decreasing
wetness turns out to be a simple floating point precision problem,
which can be easily fixed by restructuring the affected expression.

Fix (IRC reported) bad handling of Text data-block user count.

Reported on IRC by dfelinto, thanks.

Root of the issue was that opening a new text file would create
datablock with one user, when Text editor is actually a 'user one' user.

This was leaving Text datablocks in inconsitent user count, and
generating asserts in BKE_library area.

Also changed a weird piece of code related to that extra user thing in
main remapping func.

More work on Clay engine:
- Calculate normals with dfdy while waiting for a proper way to draw mesh normals.
- Added initial support for 2d texture arrays.
- Better API naming.
- Generate Matcap texture arrays and draw with it.
