This function is not supported in earlier versions.
Immediately sends all modified vertex data in the Mesh to the graphics card.
Normally it isn't necessary to call this method as love.graphics.draw(mesh, ...) will do it automatically if needed, but explicitly using Mesh:flush gives more control over when the work happens.
If this method is used, it generally shouldn't be called more than once (at most) between love.graphics.draw(mesh, ...) calls.
Mesh:flush( )
None.
Nothing.
