texture: Add GdkMemoryTexture GdkMemoryTexture is a texture implementation for holding data in memory (read: GBytes). You specify the GdkMemoryFormat that data is in and off you go. Renderers can use this to add uploads in various different formats and don't need to fallback to GDK doing the conersion on the CPU. Supported formats can be extended if we need new ones, for now I just added the relevant ones for Cairo and GdkPixbuf. The constructor is also private still, because I'm not sure we want to export GdkMemoryFormat. Wrappers that do from_cairo_surface() and for_pixbuf() do exist though.

gdk: Add GDK_MEMORY_DEFAULT This is the default memory format. I added it because it is way better than including a private header and using GDK_MEMORY_CAIRO_FORMAT_ARGB32.

gl backend: Avoid roundtripping via surface when updloading Do custom uploads rather than using gdk_cairo_surface_upload_to_gl(), because this way we avoids a roundtrip (memcpy and possibly conversion) to the cairo image surface format.
