[LUCID/iron] Unified graphics on the way ...

here are two versions of the GUI for LUCID: desktop and mobile. Apart from the obvious interface differences (desktop looks like a conventional pogram; mobile has buttons for touhscreen use) the underlying 3D graphics used different approaches in OpenGL. These are being unified so that both versions use derivatives of the same OpenGL Shader Language (OGSL) code which helps reduce code duplication elsewhere. Developers can pick the user interface, and GLSL shader version, at compile time. The new version is being tested on mobile, tablet and desktop machines. More news soon.
