Readme for OpenVG-0.2.1

Haskell bindings to ShivaVG (OpenVG implementation). Haskell OpenVG 0.1 binds to ShivaVG-0.2.0 Haskell OpenVG 0.2 binds to ShivaVG-0.2.1 I've tested the bindings on both Windows XP (MinGW/Msys) and MacOSX Leopard. On MacOSX both the 0.2 and 0.1 bindings seem work on their respective libraries. On Windows I've not been able to get the 0.2 bindings to work, so go with Haskell OpenVG 0.1 and ShivaVG-0.2.0. OTHER PROBLEMS: MacOSX - runhaskell / GHCi freeze the shell when you try to run the example TestVgu.hs. You will have to compile it first. Windows - running the test through GHCi kills the GHCi session when you close the display window. Its better to run through runhaskell. Shiva-VG (the C Library) should install quite easily on MacOSX - I installed it with the usual `configure`, `make` % `make install`. I would imagine Linux is easy too. Windows isn't at all easy - but there are instructions in the file `InstallWindows.txt`. On all platforms you will need OpenGL and GLUT and the Haskell bindings to OpenGL and GLUT installed and working.
