Fix T72682: Regression when moving markers while holding ctrl

In 2.79 when moving a marker with `G` while holding `ctrl` the marker
would snap to one-second movements. This was (probably accidentally)
removed when the Timeline Editor was removed in rB5374865523faf253.

Cleanup: Typo error

Industry Compat keymap: Properly support Grease Pencil Edit Mode

Many things weren't working correctly in GP Edit Mode, such as select/deselect/invert all, basic tools, extrude, snap etc.

Now this mode works consistently with other modes.

GPencil: Add ToDo comment

Merge branch 'greasepencil-object' into greasepencil-refactor

Merge branch 'master' into greasepencil-object

GPencil: Add missing update in previous commit of task T72897

CMake: enable FFTW for headless & bpy configurations

This caused the ocean modifier to be disabled.

Cleanup: warning

This operator was pending of fix.

BLI_kdopbvh: Deduplicate code

No need to create different callbacks for `BLI_task_parallel_range`,
these callbacks are called a few times.

GPencil: Refactor: Add SMAA as Antialiasing solution

This removes the need of MSAA and the cost associated with it.
We run edge detection on both revealage and color buffer.

However the implemntation is not perfect: The source buffers are in linear
color space and the edge detection implies gamma corrected (display) space.
This mean the algorithm fails to capture some color changes. To workaround
this, we increase SMAA_LUMA_WEIGHT which has the same effect as decreasing
SMAA_THRESHOLD. This works ok in most scenes since GPencil objects have
clean and sharply defined shapes.

minor fixes

better to string conversion for generic types

initial constant folding of multi function network
