Attempts to substitude CCGDM with an OpenSubdiv based structure
which has less abstraction levels. The missing part in this
substitude is a face pointers which old CCGDM/multires code was
using to stitch faces (averaging boundaries).
Another curial bit missing: "reshaping" of multires CD_MDISPS
to the state of new PBVH grids.
The new code is only available when OpenSubdiv modifier is
enabled (WITH_OPENSUBDIV_MODIFIER=ON) and with debug value of
128. This is so this WIP code is not interfering with current
production machines in the studio.

Didn't realize the index buffer is stored once in a BVH
and same pointer is reused. Surprisingly, simple files
were fixed with the previous fix.
Now disabled the optimization all together, and it was
simpler to just completely remove all residue of the
code. It is likely to be a different implementation
anyway, so no need to try to keep code in a semi-broken
state.
Nodes can have different number of grids, so can not so simply
re-use index buffer across nodes. For now allow re-using buffer
if number of grids matches.
The issue is, number of grids is probably almost never matches,
so in order to have this optimization working need more tricks.
Maybe we can "instance" index buffers?
Was using UI_BLOCK_LOOP to control draw style,
this meant we couldn't use popup theme colors for cases
where it the interface has the same purpose as a popup but happens
not to use this flag.
As mentioned in d81aeb60fe the alignment for multiple text boxes should all
respect the same overall padding.
Vertical alignment is fully implemented now.
During drawing, the depsgrah was tagged to update and this produced a full copy of the datablock. This tag was done in order to get the right data in drawing engine, but this added a great overhead while drawing and the response of the pen was not good.
Now, the depsgraph is not tagged and the drawing engine uses the original copy data of the buffer datablock. This is not a problem because only can draw in one window at time.
Now we can create new base color, roughness, metallic, specular, normal,
bump and displacement images, and linked them to the appropriate socket.
Also fixes image nodes inside groups not being visible.

To follow Blender standards, the name of the new primitive stroke must be different of blank object.
Also changed the default orientation of Suzanne 2D to use the same as other objects (not aligned by default)
