[Interest] Qt, QML, GraphicsSystem and display orientation

I observed a strange bug with raster graphics system.   Using that, and 
setting the screen orientation to landscape does not work.

In 4.7.4 it worked, if I started the the application in landscape. If 
started in portrait, the UI appeared in landscape in 360x360 box.  With 
the latest 4.8.0 on Symbian my landscape UI renders in upside down portrait.

If I use the default graphics system 4.8.0 orientation handling seems to 
work, pageOrientation is respected, no strange cropping etc.  But when 
using raster, no such luck.

Why am I using raster you may ask.  This is the comment in code 
explaining the issue:

// without graphics system raster X7 complains "textureQGLTexturePool 
cannot reclaim sufficient space for a 640x360"

My problem seems to be a variation of


I ignore if this a symbian specific problem, or would raster graphics 
system be broken elsewhere in the similar fashion.

Any ideas?
