PyAPI: Cleanup "Python API Overview" doc

Reword to clean up some odd grammar (mostly dangling modifiers) and
improve readability.

Differential Revision: https://developer.blender.org/D2699

Fix for crash/error drawing duplis

Drawing object centers used stack memory,
we don't want to draw these anyway so add check.

Cleanup: Trailign whitespace

Fix logic for bitwise flags in bases during deg iterator

Spotted/reported by Sergey Sharybin.

Fixup for 824bf261f773 so Cycles does not show dupli

Cycles is using rna_depsgraph, not rna_scene. Duplis are still not working there
but now at least it shows it was showing before the commit.

To show duplis in Cycles do:

- data->flag = DEG_OBJECT_ITER_FLAG_SET;
+ data->flag = DEG_OBJECT_ITER_FLAG_ALL;

Fix T51691: Shear cursor input scales w/ zoom

Use relative value from cursor movement.

Silence annoying rna warnings from Eevee

Initial implememtation for dupli objects

Now dupli groups, objects, particles, ... are all working.

This introduces a flag for the iterator to determine whether we go over
Set and dupli objects or not.

Important to remember to keep the iteration of DEG_ as readonly.

Cycles is not working well for dupli groups, and it's memleaking
for dupli particles. So for now we iterate over main objects and set
only, not dupli.

To change that go in rna_scene.c and:

-DEG_OBJECT_ITER(graph, ob, DEG_OBJECT_ITER_FLAG_SET)
+DEG_OBJECT_ITER(graph, ob, DEG_OBJECT_ITER_FLAG_ALL)

Review and suggestions by Sergey Sharybin

Suppress assert for meshes with no faces

Fix T51695: Border select fails w/ lamps

Draw order doesn't match scene order when mixing object types.

Merge branch 'master' into blender2.8

Cleanup: style

Fix View3D orientation index initial value

Would assert after transform

Fix crash using non-camera object as camera

Also sync with master to avoid conflicts

PyAPI: update to bpy.types.Operator.5.py

This is a minor update add more information on how Blender handles modal
operators. The existing docs provide a good overview, but might not be
as helpful to those unfamiliar with modal programming. This patch also
corrects a few small grammar issues.
