ImGui::ImageButton(const sf::Sprite& sprite) ignores rotation

ImGui::ImageButton(const sf::Sprite& sprite) takes the texture and position but ignores the rotation of the sprite.

Indeed, right now sf::Sprite's transform is ignored, but I can only make it work with ImGui::Image, because there's no way to draw rotated image using ImGui::ImageButton.

I think what you need to do is to make custom ImageButton, which will copy how original ImageButton is implemented, but instead use advice from this issue and use AddImageQuad instead of AddImage.

Sorry, I don't want to implement this custom ImageButton in ImGui-SFML, because it will mean that I'll need to access ImGui's private API which will make things a lot more difficult.

But I'll eventually support sf::Sprite's transform in ImGui::Image

Another workaround (which is a lot easier!) is to draw sprite onto sf::RenderTexture and then pass it into ImageButton overload for sf::Texture. You're likely to encounter #35 then, and if you do - I'll add Image/ImageButton overload for sf::RenderTexture ASAP.

I am now using the workaround of drawing the rotated sprite to a RenderTexture and flipping it to counteract #35.

Okay, I'll add overload for sf::RenderTexture soon

Could you please actually add that overload? :s

"Soon" was 1.5 years ago... Shame on me.
Okay, I'll try to add it this week. But if someone provides a PR it would get into master even quicker. ;)

Update: fix for RenderTexture is not in master and released in v2.2

If I manage to do #87, the sprite transform might be taken into account. I'll see what i can do.
