Don't use EGL surfaces for translucency with 32MB GPU chip.
Add dynamic GPU chip detection on Symbian to decide if
translucent EGL surfaces can be used. With 32MB GPU memory
there is not enough memory to create for example transparent
video overlay widgets and that's why hw surfaces must not
be used.
