Effect used the display size which caused windows being larger than either width or height not to be captured correctly. Now it uses the window size for the offscreen texture which also requires to adjust the modelviewprojection matrix. As an unrelated change the pointer to GLRenderTarget and GLTexture are changed to a QScopedPointer and some variables which got moved around are consted. BUG: 312851 FIXED-IN: 4.11 REVIEW: 108258
