Subject: Get the image of the FBO of a effect texture
X-Git-Tag: qt-v5.0.0-alpha1~1873
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=15e62e98ad6fa73f052113c158b24549b7b28e4f;p=profile%2Fivi%2Fqtdeclarative.git

Get the image of the FBO of a effect texture

The Qml Designer needs this image because every item in the text file is
rendered in an external process in an image and send over a socket to the
main process.
