Besides the comment in T7878 regarding the possible merging of this class with Efl.Flip, I am not sure {up, down, left, right} are sensible names for a rotation. What does it mean that an icon is oriented "to the right"?
How about we rename the enum ROTATION_0, ROTATION_90, etc ?

After a lengthy brainstorming session:
- Rename this enum to Efl.Gfx.Image_Orientation
- Turn it into a bitfield and include flipping values in both axes
- Use it in all places where Efl.Orientation was used except in Efl.Ui.Layout_Base.theme_rotation_apply, that should be turned into an int.
- Delete Efl.Orientation and Efl.Flip.

After that commit, it now looks like this and I think it's good to go:
enum @beta Efl.Gfx.Orientation
{
[[An orientation type, to rotate and flip images.
This is similar to EXIF's orientation.
Directional values ($up, $down, $left, $right) indicate the final direction in
which the top of the image will be facing (e.g. a picture of a house will have
its roof pointing to the right if the $right orientation is used).
Flipping values ($flip_horizontal and $flip_vertical) can be additionaly added
to produce a mirroring in each axis.
Not to be confused with @Efl.Ui.Dir which is meant for widgets, rather
than images and canvases. This enum is used to rotate images, videos and
the like.
