This reverts commit 5aa19be912 and b4a721af69.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.
There are a lot of cases here where deciding for removal is a bit tricky.
Many features have options for "use_particles" and similar settings. Only
features which actually store a particle object reference or work on actual
particle data have been removed.
Made keyap use the same select_or_deselect_all operator
as used for maya keymap instead of tricks with deselect_all.
Solves issue with selection in editor mode (reported as #3
in the original bug report).
Two main things:
- Made a python operator for selection in a viewport
which will de-select everything if nothing is under
the mouse.
To do so needed to modify VIEW3D_OT_select, so invoke
sets mouse location which is later used by exec
function.
This way it's possible to select stuff from python
defined operator.
Not best-ever solution since ideally exec() shall not
do OpenGL stuff, but we've got this issue in some
other operators. We'll solve this later.
- Used a keymap from Gianmichele Mariani as a reference,
updated his keymap to latest changes in operators.
We shall match Maya keymap much better now, thanks
for the keymap dude!
