commit 296e8c22b039fd5669ad95375733bf214b23d71e
Author: Oleksandr Shcherbina <o.shcherb...@samsung.com>

evas.canvas3d: support static LOD technic
Summary:
Main flow: add several meshes(with different number of polygons) in one
node,
enable LOD for node, set boundary distances to choose need mesh depend on
distance
to the camera node, render only need mesh. Add API's enable lod in
evas_canvas3d_node module and set boundary distance to module
evas_canvas3d_mesh module Refactored function
evas_canvas3d_node_mesh_collect
to calculate distance. Refactored _scene_render to have possibility pass to
the
render only need LOD mesh.
