[Qt-interest] Fixed a non-aligned memory access for SH4 platform in QT Embedded 4.5

[fabio]

Hi,

I'm using qt-embedded 4.5 on a sh4 architecture target.
I had some problems related to non-aligned memory access in
qt_blend_argb24_on_rgb16(..) function in
src/gui/painting/qblendfunctions.cpp.
I solved this bug and report it in Qt Bug Report Form with patch file
attached and now qt-embedded on SH4 are working faster.
Can you add this patch in qt-embedded source code in order more properly
with SH4 platform.

Best Regard
