cogl: Include DRM 4CC conversions into CoglPixelFormat

This is at the moment still part of both MetaRendererNative and
MetaDmaBuf, which means duplicated effort in code sections only barely
related to color formats. By doing this, we can keep more of the pixel
format code together, which is more future-proof as we want to add
support for new pixel formats (like YUV-based ones).

-/**
- * SECTION:clutter-behaviour-path
- * @Title: ClutterBehaviourPath
- * @short_description: A behaviour for moving actors along a #ClutterPath
- * @Deprecated: 1.6: Use #ClutterPathConstraint and clutter_actor_animate()
- *   with the #ClutterPathConstraint:offset property instead.
- *
- * #ClutterBehaviourPath interpolates actors along a defined path.
- *
- * A path is described by a #ClutterPath object. The path can contain
- * straight line parts and bezier curves. If the path contains
- * %CLUTTER_PATH_MOVE_TO parts then the actors will jump to those
- * coordinates. This can be used make disjoint paths.
- *
- * When creating a path behaviour in a #ClutterScript, you can specify
- * the path property directly as a string. For example:
- *
- * |[
- * {
- *   "id"     : "spline-path",
- *   "type"   : "ClutterBehaviourPath",
- *   "path"   : "M 50 50 L 100 100",
- *   "alpha"  : {
- *      "timeline" : "main-timeline",
- *      "function" : "ramp
- *    }
- * }
- * ]|
- *
- * If the alpha function is a periodic function, i.e. it returns to
- * 0.0 after reaching 1.0, then the actors will walk the path back to the
- * starting #ClutterKnot.
- *
- * #ClutterBehaviourPath is available since Clutter 0.2
- *
- * Deprecated: 1.6: Use #ClutterPath and #ClutterPathConstraint with
- *   clutter_actor_animate() instead.
