Render Texture: "Error #3605: Sampler 0 binds an invalid texture" when not cleared or drawn before actual Image rendering about starling-framework HOT 3 CLOSED

Hey Aurélien,
this is "as designed", although you are perfectly right: this information needs to be part of the documentation! I just extended the asdoc info accordingly.

I also had a look if I could automate this — call "clear" automatically on first render if it hasn't yet happened – but that is not so easy. The error occurs when the image/quad/mesh that has the texture assigned is rendered; and from the perspective of that object, it's just a normal texture, like any other, so there's no way to "ask" if the texture is ready. And the RenderTexture itself isn't notified that it's being rendered at all.

So I guess the best thing to do is inform users about this requirement (it's easy to follow, anyway), and otherwise leave this as it is.

In any case, thanks for making me aware of this!
