background-actor: Use MetaBackgroundContent
MetaBackgroundActor is still necessary for culling purposes,
but now the actual rendering of the background is delegated
to MetaBackgroundContent, as well as the sizing information.

- * SECTION:meta-background-actor
- * @title: MetaBackgroundActor
- * @short_description: Actor for painting the root window background
- *
- */

-/*
- * The overall model drawing model of this widget is that we have one
- * texture, or two interpolated textures, possibly with alpha or
- * margins that let the underlying background show through, blended
- * over a solid color or a gradient. The result of that combination
- * can then be affected by a "vignette" that darkens the background
- * away from a central point (or as a no-GLSL fallback, simply darkens
- * the background) and by overall opacity.
- *
- * As of GNOME 3.14, GNOME is only using a fraction of this when the
- * user sets the background through the control center - what can be
- * set is:
- *
- * A single image without a border
- * An animation of images without a border that blend together,
- * with the blend changing every 4-5 minutes
- * A solid color with a repeated noise texture blended over it
- *
- * This all is pretty easy to do in a fragment shader, except when:
- *
- * A) We don't have GLSL - in this case, the operation of
- * interpolating the two textures and blending the result over the
- * background can't be expressed with Cogl's fixed-function layer
- * combining (which is confined to what GL's texture environment
- * combining can do) So we can only handle the above directly if
- * there are no margins or alpha.
- *
- * B) The image textures are sliced. Texture size limits on older
- * hardware (pre-965 intel hardware, r300, etc.) is often 2048,
- * and it would be common to use a texture larger than this for a
- * background and expect it to be scaled down. Cogl can compensate
- * for this by breaking the texture up into multiple textures, but
- * can't multitexture with sliced textures. So we can only handle
- * the above if there's a single texture.
- *
- * However, even when we *can* represent everything in a single pass,
- * it's not necessarily efficient. If we want to draw a 1024x768
- * background, it's pretty inefficient to bilinearly texture from
- * two 2560x1440 images and mix that. So the drawing model we take
- * here is that MetaBackground generates a single texture (which
- * might be a 1x1 texture for a solid color, or a 1x2 texture for a
- * gradient, or a repeated texture for wallpaper, or a pre-rendered
- * texture the size of the screen), and we draw with that, possibly
- * adding the vignette and opacity.
