My first attepmt I added a second loop to check if processing should
stop. This attempts to optimize by using the original loop (one loop).
Also resets `elapsed` time on finish of tween which fixes `tell()`.
I've made the following changes:
- make `is_active` the main way of keeping track of tween
processing/activity, meaning that `is_active` will now return
`false` if all tween actions have finished or if it isn't started
or if it was stopped via `set_active(false)` or any other mode
- removed is_stopped because is redundand now
The above meant that we don't have to keep track of yet another variable
`available` since everything is based on `*processing_internal` so I
removed it, likewise it's own local `processing` variable was removed,
as well as the "double" `_set_process` which it feels more like a hack.
What wasn't changed:
- `tell()` still returns max value (i.e. `== get_runtime()` when all
tweens `finish`)
*More testing is needed*. So far I've tested repeat on/off, delay,
`is_active()` working corretly, `set_active(true), set_active(false)`,
but probably more tests are necessary, all the resets, stops, resume
etc.
Rename the option in the right click menu in the Scene nodes
because Discard Instancing is confusing (it could imply deleting the
instance). I renamed it to Make Local which is used for example in
Blender as well when talking about appending assets from other files.
I think it's clearer. Or it can be renamed to Make Instance Local, but I
thought it's a bit oo long so I went just with Make Local as this option
appears in the menu only when the node is an instance anyway.
These files did not serve a real purpose since `icon.png` can be used
as the AppImage icon, and a .desktop file can be found at
`misc/dist/linux/godot.desktop` with the same contents.
- Add (Csc/Vbc/Fsc)ToolExe environment variables when running Mono's MSBuild.
- Fix directory for the 'mono_assemblies_output_dir' argument being created with the '#' top level directory token as part of its name.
- Allow to build with 'mono_static=yes' on Unix without specifying a mono prefix. The build script will try to find the mono prefix using the output from pkg-config.
