WIP: wayland: add basic support for non-RGBA textures
Up until now, we didn't support sending YUV textures to the Wayland
server. This was for several reasons:
* We draw onto an RGBA framebuffer, so any other color format needs to
be converted to that color space. Since we don't want to lose a lot of
performance, this is ideally done on the GPU (using shaders).
* YUV formats can consist of several planes (for example NV12, a common
format in decoded video frames consists of a Y-plane and a subsampled
UV-plane). Mutter always assumed that any texture it got was
representable by a `CoglTexture`, which does not have this kind of
concept.
To deal with this, we introduce a new "texture": a
`CoglMultiPlaneTexture` which consists of multiple CoglTextures, each
representing a plane in the texture we got. It also provides support
for CoglSnippets which can convert the colorspace if necessary.
What changes are in this commit:
* Introduce a new CoglMultiPlaneTexture object. Right now it is not
implemented as a CoglTexture to prevent any confusion (but it is
somewhat related to CoglMetaTexture)
* Added some extra values to the CoglPixelFormat enum that deal with YUV
* Make the necessary changes in MetaWaylandBuffer, so that it knows how
to deal with incoming buffers (for example EGLImages and shm buffers)
* This also introduces some changes in MetaDmaBuf, as that is also a
different kind of buffer we can receive from wayland.
Acknowledgements
* There was a lot of prior art already done by the authors of Weston,
CoglGstVideoSink and ClutterGstSink
* My employer Barco for allowing me to work on this

+ * @short_description: A non-primitive texture that can have multiple planes.
+ *
+ * #CoglMultiPlaneTexture allows one to deal with non-trivial formats that
+ * have multiple planes, requires subsampling and/or aren't in RGB. A common
+ * example of this are decoded video frames, which often use something in the
+ * YUV colorspace, combined with subsampling.
+ *
+ * The basic idea of a #CoglMultiPlaneTexture is the following:
+ * - Each plane is represented by a separate #CoglTexture. That means that you
+ * should add each of these planes as a layer to your CoglPipeline.
+ * - When dealing with a color space that is not RGB, you can ask the
+ * #CoglMultiPlaneTexture to create a shader for you that does the conversion
+ * in the GPU.
+ * - In case you need to deal with memory access in a format with subsampling,
+ * you can use cogl_multi_plane_texture_get_width() and its analogous version
+ * for the height to get the correct size of the texture.
