[Qt-interest] QT-OpenVG how to

[Amit Pundir]

According to QT labs announcement of OpenVG support in Qt 4.6:
-------------------------------
Qt/Embedded support - some experimental screen drivers have been
written internally but every vendor’s EGL is different, which makes
Qt/Embedded difficult to support for both OpenVG and OpenGL/ES.
-------------------------------

Can I have access to those experimental screen drivers because when I
tried to run the existing Qt-OpenVG example it gave me the following
errror:
"Not using OpenVG: use the '-display' option to specify an OpenVG driver" ?
