Release 0.2

New features:

• Incremental rendering for large point clouds, including dynamic
  estimation of allowable interactive point count.
• Save and load shaders: Menu items for the GUI, and a command line
  option to set the shader on startup. Also install shaders rather than
  embedding them to improve hackability.
• Single instance support: new files now open in an existing displaz
  instance, unless -noserver is specified on the command line
• Drag and drop to open files
• Html documentation in GUI
• Binary installer for windows

Tweaks:

• New point colouring mode based on file number in default shader
• Proper console help text and console debug output on windows
• Log Euclidian distance between consecutive selected points
• Support reading colour from .ply files
• Cylindrical projection shader
• Increase near clip plane to reduce z-fighting
• Carefully acknowledge with third party licenses in binary distribution
• Version numbering based on git-describe

Bug fixes:

• Fix for older ATI drivers which require #version to come before #define
• Fix display of zero point size on non-nvidia hardware
• Fix uninitialized shader variables when loading from text file
• Fix crash when opening text files containing zero points

Internal changes:

• Octree data structure for better rendering and search
• Make building the dependencies easier
• Rearrange source tree
