Fix error splitting convex faces

Created double faces, leaked memory.

Fix T48654: outline text visible while renaming

Both button and rename text would draw while renaming,
caused issues with some themes.

Fix region_2d_to_origin_3d not working with ortho view

In some cases when:
* the viewport was in the camera mode
* the camera was ortho
* the view was not fitting (as oppose to use HOME)

region_2d_to_origin_3d would misbehave (and consequently region_2d_to_location_3d).

Sample addon to test it:
```
import bpy

from bpy_extras.view3d_utils import (
region_2d_to_location_3d,
)

from mathutils import (
Vector,
)

class MoveXYOperator(bpy.types.Operator):
"""Translate the view using mouse events"""
bl_idname = "view3d.move_xy"
bl_label = "Move XY"

@classmethod
def poll(cls, context):
return context.object

def modal(self, context, event):
if event.type == 'MOUSEMOVE':
self.move(context, event)

elif event.type in {'LEFTMOUSE', 'RIGHTMOUSE', 'ESC'}:
return {'FINISHED'}

return {'RUNNING_MODAL'}

def invoke(self, context, event):
if context.space_data.type == 'VIEW_3D':
self.ob = context.object
context.window_manager.modal_handler_add(self)
return {'RUNNING_MODAL'}
else:
self.report({'WARNING'}, "Active space must be a View3d")
return {'CANCELLED'}

def move(self, context, event):
xy = region_2d_to_location_3d(
context.region,
context.space_data.region_3d,
(event.mouse_region_x, event.mouse_region_y),
Vector(),
).xy

self.ob.location.xy = xy

def register():
bpy.utils.register_class(MoveXYOperator)

def unregister():
bpy.utils.unregister_class(MoveXYOperator)

if __name__ == "__main__":
register()
```

Text Editor: auto-complete removed entire word on undo

Correct update issue caused by recent commit

VSE effects within a meta-strip could fail to update on cancel.

VSE: minor drawing glitch with meta's

Meta contents could obscure meta selection outline, draw after.

Fix VSE updating effects within metas

Missing update caused internal lengths to be wrong.

Cleanup: Remove outdated comment, visibility layers in kernel have been removed.

FileSpace cleanup: make ED_path_extension_type public.

Maybe we should move it to BLI, but not sure how, and where (and its defines
are SpaceFile's ones, meh :| ).

Write .blend file: refactor & fixes re ID block itself.

Factorized writing of ID block's data (so far, only IDProps) into own helper func.
This also fixes missing IDProp (aka custom data) saving from GreasePencil and Library
datablocks (and add comment about why we do not save WM IDProps).

Finaly, it ensures all ID-related data are written immediately after the ID itself
(was not the case for all data types previously, some were writting their own data
before IDProps). This is not a fix (.blend file format does not enforce any order
on sub-data of datablocks, they only have to be after datablock struct itself in file),
but makes things more consistent.

Correct sequencer transform check

Check to avoid operating on same strip multiple times wasn't working.

Harmless but better make it functional.

Fix T48649: VSE meta-strip overlap shuffles recursively

fix T48602: Changed The Collada validator to treat faces with < 3 verts as Warning and let the Mesh Validator take care of the cleanup

Fix T48613: Bump mapping in cycles is not shown on the viewport when the material use node groups

Fix T48154: Decimate topology changes with scale

This can't be avoided completely, however the threshold used can be much lower.

Usual UI/i18n message fixes.

Made incremental snapping intervalls smaller for UV editor

Before the intervall was set to 0.125 which effectively resulted in 8 positions across the UV space (per axis).
I halved that value, holding shift enables an even finer movement.

This change was ported over from my soc-2016-uv_tools branch after talking with howardt, ideasman42 and hackerman-

Curve Fitting: add high-quality flag

When this flag is set - even when the curve error is under the threshold,
keep attempting a better fit.

Enable this for freehand drawing, since it gives nicer results and isn't noticeably slower.
