[Bf-webcontent] Call for artwork

[Francesco Siddi]

The new blender.org relies on beautiful graphics for headers and carousels.

The Features section also has a new layout and needs good and
up-to-date screenshots or examples of the features being described.

What is needed:
- High quality images that can fit an horizontal format, at least ~2K
width, ~1K height.
- These images should easily allow typography overlay (not so cluttered)
- Screenshots from different areas featuring the artwork (wireframe
models, compositing, image painting, and such). Unless needed for that
specific snap, don’t display just a single model, let’s show that
Blender can handle a whole production scene in the same .blend.

The screenshots should feature the default theme, for consistency. Is
nice to show Blender supports different themes but we can do that
specifically.

If anyone is available to help out on this it would be appreciated!
