    Description

      I have multi QQuickRenderTarget for a QQuickWindow, I want to render a part of QQuickWindow to a QQuickRenderTarget.
      The QQuickRenderControl::render always from 0,0 position render to the QQuickRenderTarget.

      For an example:

      
QQuickRenderTarget rt1 = QQuickRenderTarget::fromOpenGLTexture(0, ..., QSize(100, 100));
QQuickRenderTarget rt2 = QQuickRenderTarget::fromOpenGLTexture(1, ..., QSize(100, 100));

QQuickRenderControl *rc = window->renderControl();

window->setRenderTarget(rt1);
rc->render(QPoint(0, 0));

window->setRenderTarget(rt2);
rc->render(QPoint(100, 0));
