5bfeaf6cc1 Cleanup: group VBO attributes in a struct 
Some names are a bit arbitrary,
this makes it clear which names are VBO attributes.

3d6361aa9c Cleanup: clarify select terminology 
In mesh cache we have select: color, id, bool.
Current naming didn't make this clear.

89483c73fd DWM: write mesh data to the VBO directly 
Was using intermediate functions to store each data type.
This is still done in some places (for more involved access).

For basic data: coords, normals, colors..etc this is unnecessarily indirect.

77d0aec3d1 Mesh Batch Cache: Use compressed format. 
We don't compress UV by default because that would mean restricting them to [0, 1]
Leaving all other code for later settings switch.

e053fade99 Mesh Batch Cache: get rid of the ORCO VBO data, and reconstruct it in shader. 
With only one MADD instruction we recover the orco data and reduce both the storage and the fetching cost of an attrib layer.

38125d0499 Mesh Batch Cache: Define Compressed format for shading data. 
Deactivated by default.
All shading attribs can be packed to take less VRAM at the cost of precision (not noticable in this case).
UVs can be packed into I16 but that limits their positions into the [-1, +1] range.

This could be a setting option in the future.

0dd766b043 DWM: Share VBO positions & normals for mesh cache

Use multiple VBO's per batch for more efficient storage.

19f86a3d5f Mesh Batch Cache: Add support for uv/vcol/tangent data layers. 
This is a bad implementation waiting for some improvement that are :
- Gawain support for multiple names. -> will remove duplication of attribute alloc
- Glsl safe name string escaping. -> will remove any risk of hash colision.

Old glsl drawing was relying on attribute being choosen by DerivedMesh at drawing time.
For this reason, we declare all possible attrib "name" for each data layer inside the batches.
In the glsl code, we declare required data by type and name.
Then Gawain only bind vbos if names correspond.
This is way cleaner as we do not need to access the CD itself when drawing.

One other problem is that the hash maybe 11 caracters long and rapidly overload gawain's attrib name buffer.

041a50291b Eevee: Make default shaders works. 
- Added New Batch cache routine to get the split mesh for each material. (optimization needed)
- Did some shader modifications to create default_frag and support a somwhat correct fresnel for lamps (to finish)
