Enable cross-process glyph cache for OpenVG graphics system on Symbian.
This introduces a specialized OpenVG font cache for the Symbian
platform. By using RGlyphDataIterator we can create a VGImage to store
inside a VGFont without having to upload our own glyph image. This
works by utilizing RSgImage which can be used to share handles to
graphics memory across processes thus allowing glyph images to be
shared by multiple processes and reducing graphics memory usage.
