text: "<b>Rendering</b><br/>Qt5 has brand new rendering backend 'QML SceneGraph' which is optimized for hardware accelerated rendering. This allows to take full gains out of OpenGL powered GPUs on desktop and embedded devices. Not just performance, new Qt5 rendering backend also allows features which have not been possible earlier."

text: "<b>ShaderEffects</b><br/>Qt5 supports ShaderEffect and ShaderEffectSource QML elements which allow writing custom GLSL shader effects.
