The CoglBitmap struct is now only defined within cogl-bitmap.c so that all of its members can now only be accessed with accessor functions. To get to the data pointer for the bitmap image you must first call _cogl_bitmap_map and later call _cogl_bitmap_unmap. The map function takes the same arguments as cogl_pixel_array_map so that eventually we can make a bitmap optionally internally divert to a pixel array. There is a _cogl_bitmap_new_from_data function which constructs a new bitmap object and takes ownership of the data pointer. The function gets passed a destroy callback which gets called when the bitmap is freed. This is similar to how gdk_pixbuf_new_from_data works. Alternatively NULL can be passed for the destroy function which means that the caller will manage the life of the pointer (but must guarantee that it stays alive at least until the bitmap is freed). This mechanism is used instead of the old approach of creating a CoglBitmap struct on the stack and manually filling in the members. It could also later be used to create a CoglBitmap that owns a GdkPixbuf ref so that we don't necessarily have to copy the GdkPixbuf data when converting to a bitmap. There is also _cogl_bitmap_new_shared. This creates a bitmap using a reference to another CoglBitmap for the data. This is a bit of a hack but it is needed by the atlas texture backend which wants to divert the set_region virtual to another texture but it needs to override the format of the bitmap to ignore the premult flag.
