From edddadd88950f22f6d813e50acdcf2711d3d5a84 Mon Sep 17 00:00:00 2001 From: Jason Barron Date: Tue, 12 Oct 2010 10:58:11 +0200 Subject: Add support for Qt::WA_TranslucentBackground with OpenVG on Symbian^3 S^3 does not have a client side API to support semi-transparent EGL surfaces so if this flag is enabled for a particular widget, then we should return a raster surface instead of a VG surface. Raster surfaces can still be semi-transparent but will be slower to render to.
