Release 1.10.1.1

For 1.10.1:

• Gloss no longer consumes CPU time when displaying static pictures.
• Added displayIO wrapper for mostly static pictures, eg when
  plotting graphs generated from infrequently updated files.
• Allow viewport to be scaled with control-left-click drag.
• Rotation of viewport changed to alt-left-click drag.
• Preserve current colour when rendering bitmpaps.
• Changed to proper sum-of-squares colour mixing, rather than naive
  addition of components which was causing mixed colours to be too dark.
  Thanks to Thomas DuBuisson
• Allow bitmaps to be specified in RGBA byte order as well as ABGR.
  Thanks to Gabriel Gonzalez
• Package definitions for building with Stack.
