sf::RenderTarget and display()

[Ancurio]

Just a small confusing thing that I noticed, but why is 'display()' not a pure virtual function
of sf::RenderTarget? It has the same signature in both RenderTexture and RenderWindow o.o

[Laurent]

Because it's a virtual function of sf::Window.

In fact, RenderTexture::display() has the same name as RenderWindow::display() because the usage is similar, but:
- it's not required at RenderTarget level
- internally it does a totally different thing

Ah, I see, thanks.
Yeah, you're right, as far as I can tell RenderWindow::display() flips buffers,
whereas the single-buffered RenderTexture just corrects the Y-axis.

The reason I asked was because I needed a "finalize draw" method that works from RenderTarget,
but it's trivial to do that myself ^^
