Render routine:

- Render pass shadow map

  - one draw call, write to one color attachment with 6 layers

- Render pass Gaussian filter (x direction)

  - one draw call, write to six color attachments with single layer

- Render pass Gaussian filter (y direction)

  - same as above

- Render pass on screen
