Draw a mesh.
DrawMesh draws a mesh for one frame. The mesh will be affected by the lights, can cast and receive shadows and be
affected by Projectors - just like it was part of some game object. It can be drawn for all cameras or just for
some specific camera.
Use DrawMesh in situations where you want to draw large amount of meshes, but don't want the overhead of creating and managing game objects. Note that DrawMesh does not draw the mesh immediately; it merely "submits" it for rendering. The mesh will be rendered as part of normal rendering process. If you want to draw a mesh immediately, use Graphics.DrawMeshNow.
Because DrawMesh does not draw mesh immediately, modifying material properties between calls to this function won't make the meshes pick up them. If you want to draw series of meshes with the same material, but slightly different properties (e.g. change color of each mesh), use MaterialPropertyBlock parameter.
Note that this call will create some internal resources while the mesh is queued up for rendering. The allocation happens immediately and will be kept around until the end of frame (if the object was queued for all cameras) or until the specified camera renders itself.
