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.

texture: Refactor downloading Pass a format do GdkTextureClass::download(). That way we can download data in any format. Also replace gdk_texture_download_texture() with gdk_memory_texture_from_texture() which again takes a format. The old functionality is still there for code that wants it: Just pass gdk_texture_get_format (texture) as the format argument.

gl: Refactor texture uploading Don't pass texture + rect, but instead have gdk_memory_texture_new_subtexture() and use it to generate subtextures and pass them. This has the advantage of downloading the a too large texture only once instead of N times.
