Revert "Cmake build missing geom icons"

This reverts commit 468474a653c976615306254dfcc33a85a0b872a1.

Fix diagonal line artifact in view navigate icons.

Thanks to Cl�ment for finding the fix!

Python API: add loop triangles access, remove tessfaces.

Loop triangles are tessellated triangles create from polygons, for renderers
or exporters that need to match Blender's polygon tesselation exactly. These
are a read-only runtime cache.

Tessfaces are a legacy data structure from before Blender supported n-gons,
and were already mostly removed from the C code.

Details on porting code to loop triangles is in the release notes.

Cmake build missing geom icons

The icons themselves (their .dat) still need to be updated. But this will make
sure they are part of the pack next time the icons are updated.

Fix material properties Python error when there is no active object.

Modifier: Fix cage option for deform modifiers

Show-on-cage and show-in-editmode options now work as it did in 2.7x
(but only for deformation).

Fix modifier cage option being overwritten

Editmesh modifier calculation behaved as if eModifierMode_OnCage
was enabled for all modifiers.

Remove assignment after all modifiers are calculated.

Cleanup: naming

Correct bad statvis default in recent commit

Cleanup: naming

- mesh_calc_modifiers & editbmesh_calc_modifiers
now follow similar naming.
- me and mesh were too easily confused in mesh_calc_modifiers
(remove 'me', access ob->data).

Cleanup: add back add_shapekey_layers to modifier stack

Looks like this might not be used, add back just in case.

Cleanup: uncomment statvis calculation (still disabled)

Modifier: use simplified bmesh -> mesh conversion

BMesh: simple bmesh -> mesh for evaluation

Copied from CDDM_from_bmesh, the modifier stack doesn't
need to handle shape keys, vertex parents or selection history
(needed for mode switching).

RNA: Always keep at least one element in snap_mode.

Modifier: remove derived-mesh for sculpt crazy-space

Fix for VIEW3D_OT_snap_selected_to_active

There is no active bone data in the cowed edit armature.

This was introduced on rBe12df10120a0, back when we hoped the depsgraph
would fullfill all our hopes and dreams.

Before the single-context-editing depsgraph reality came crashing on us.

Cleanup: prefer parenthesis over breaking lines
