UVs need specific data in the VBO, which is not computed unless the shaders assigned to the mesh actually use UVs. When adding UVs to the shader, the VBOs were not being recomputed to include the required data. This adds a DEG relation between the shader and the mesh, and recomputes the required data if the shader changed. Thanks Sergey, for all the DEG stuff...
