[Adnn]

closes #121.

• Prepare migration work, by duplicating current Renderer.
• Port code for Model (Node) loading.
• WIP porting the mesh rendering: first results.
• Fix model rendering, render all instances.
• Fix "normalized" suffix handling for vertex attributes.
• Implement a "ModelLoader" sandbox simulation.
• Implement indexing into the phong material for renderer v2.
• Complete the material interaction with the Phong reflection model.
• Copy resources, revert changes made to renderer_V1 resources.
• Restore (diffuse) color texturing.
• Fix an issue with empty "upsampled" dirs, use relative paths.
• Dump more information when running "asset_processor".
• Implement a value correction for specular exponent.
• Fixup texture upsample folder.
• Revert "Implement a value correction for specular exponent."
• Implement a value correction for specular exponent.
• Factorize texture parameters reading.
• Store and read normal maps from binary files.
• Add vertex tangents to the binary file, use them for normal mapping.
• Make the assimp importer more verbose, to diagnose issues.
• f
• Make dumpTextures() even more complex...
• Adapt snacgame to work with the current partial port to renderer V2.
• Fix shaders for Viewer app.
• Handle filetype better in Viewer app, disable default cube and triangle.
• Intoduce rigging in Viewer's shaders, and review a bit Rigging.h
• Start handling Assimp bone data, dump vertex joints/weights attributes.
• Dump the Rig on Nodes when present, display bone name in Viewer gui.
• Handle "NOMINMAX" macro via the CMake scripts.
• Implement a DebugRenderer (in V2) for DebugDrawer V1.
• Write joint information in the .seum file.
• Transform debug skeleton so it aligns with the model.
• Handle Animations in seum file, animate skeletons in Viewer.
• Refactor dumpAnimations() to handle 1 key animations (static poses).
• Get a first iteration of skeletal animation in the Viewer.
