Annotations: Restore 3D View support for annotations (WIP)

Initial support for getting annotations to show up in the 3D
viewport again. WIP and slightly hacky, but it restores basic
working functionality so we can focus on polishing the "new" parts.

Ultimately, the way these callbacks are integrated into the
drawing loop will probably need to change. For example,
* Perhaps we might need a full overlay engine for this one case
(as for motionpaths), though that may also be overkill, and would
further split the code in different places.
* The draw order (relative to manipulators) needs review. It probably
should be below both sets of manipulators, not sandwiched between them.

Other notes:
* For this to work, we currently need to use the original (non-evaluated)
scene data, or else we don't get the newly drawn strokes, as the
scene->gpd stuff isn't copied by COW yet.

Annotations Keymap: Restore D-RMB for eraser

Cleanup: Remove redundant code + note some code issues to fix

Set annotions drawing mode always on top

The annotations must be visible on top of any other object in the scene.

Offline, DPIX, Snake working. no F12. DPIX draw intersection if cached.

Fix render type name error

Cleanup code

Fix draw back error due z-depth precission

The value 1.0 makes the image disappear.

Fix problem when increase viewport qualitty

The reason of the problem was the precission of the background buffer. The original value was not enough when viewport qualitty was > 0.1

Cleanup unused extern definition

This was part of old VFX modifiers.

Fix again the pointer name for textures

removed line styles from SceneLANPR
