Object Mode: Add stencil test to remove object outlines inside the silouhette.

It also adds nice occluded silouhette information for selected objects that are behind visible objects.
This methods is really heavy because it needs to render the wires twices.

Fix shader compilation.

GPUTexture: Add support for depth_stencil textures.

Eevee: Initial commit

Basic support for lamps. Only diffuse.

Draw Manager: Created a general fullscreen shader.

Cleanup: use return args last and 'r_' prefix.

Add tabs as standard button types

NOTE: This is really a backend-only implementation, nothing is changed in the UI

Adds a tab button-type and the basic drawing and handling code for it.
More work needs to be done on it, but idea is to get in ready for usage in the
topbar.

Avoid duplicating layout when activating workspace with used layout

We now fall-back to the first un-used layout we can find, we only create
a new one if none can be found.
