Yes. Several. Because of that, there was a big discussion about this. The result was that the WebGL version of OES_texture_float was modified to say that implementations may also support rendering to FP textures. Developers have to be sure to call gl.checkFramebufferStatus after attaching an FP texture to an FBO and be prepared for it to return FRAMEBUFFER_UNSUPPORTED.Interesting, thanks Mark. Shouldn't we fix this? Is there any WebGL app using FP rendering?
