Large Flickable does not render

Flickable elements with a big size don't render and cause errors such as :

QOpenGLFramebufferObject: Framebuffer incomplete attachment.
QOpenGLFramebufferObject: Framebuffer incomplete, missing attachment.

When asking on IRC I was told that it was due to Flickable rendering on a GL texture whose size may be fixed by the hardware.

Woudln't it be possible to, either :

• detect when contentWidth > hardware size and render the flickable in multiple textures ?
• instead of drawing on a large texture, draw on a small texture the size of the viewport and make the objects move over it ?
