Added compareDrawSettings callback to driver mesh's callbacks which are
drawing textured faces (mapped and not mapped). This new callback checks
if two faces are drawing with the same settings (testures, shading etc)
and if they not, flush of faces happens into ogl using glDrawArrays and
next face would be drawn with it's own settings.
Currently implemented compareDrawSettings is used to resolve issue from
bug report only, probably there are extra places where this callback is
needed, but haven't seen configuration where current logic will fail,
so it should be ok.
Also reordered arguments passing to drawMappedFaces DM's callbacks,
so now all drawing callback are accepting list of callbacks and then
userData, instead of using mixed order of callbacks and userData which
was a bit confusing to work with.
This commit fixes:
- #26410: VBO & multitexture doesnt work
- #29464: VBO enabled causes UV coruption
from Andrew Hale (trumanblending), with some edits to use these in mathutils.Vector added.
Added Functions:
- dot_vn_vn - Dot product of two arrays
- normalize_vn_vn - Normalize an array and store the result in a second array
- normalize_vn - Normalize an array inplace
Renamed Functions:
Some functions have been renamed to make them consistent with the naming conventions used by fixed length array functions.
- fill_vni to fill_vn_i
- fill_vn to fill_vn_fl
effect for a render engine using new shading nodes. In short:
* No longer uses images assigned to faces in the uv layer, rather the active
image texture node is what is edited/painted/drawn.
* Textured draw type now shows the active image texture node, with solid
lighting.
* Material draw mode shows GLSL shader of a simplified material node tree,
using solid lighting.
* Textures for modifiers, brushes, etc, are now available from a dropdown in
the texture tab in the properties editor. These do not use new shading nodes
yet.

- 2 new navmesh operators, reset and clear navmesh data.
- rename operators to be more consistent with existing names.
- some minor edits to draw function, was getting the custom data for every index when it already had the array.
- only pass if the mesh has vertex colors to drawParams() rather then the mcol its self, this saves a lookup on the color.
- drawing textures in editmode with no vertex colors would still lookup vertex colors on each face, instead cache this info for all faces.
