David Capello ce77a38303 Fix base::Observers impl: Copy the whole list of observers before we start iterating them (fix issue 427) 
There are cases where we need to modify the list of observers of certain
entity when we are in a notification loop (i.e. iterating its observers).
E.g. A general update notification about the current document to all its
observers could create the mini editor, which is a DocumentObserver, so
a new observer is added to the list in the same notification loop.

Anyway, as we cannot modify the observer list (std::vector) when we are
notifying them (any modification in the std::vector invalidates
its iterators), the fix is quite easy (but not optimal): we can create
a copy of the observers list so we can iterate the list.

Note: If we have performance issues about this, we could try a std::list,
but at the moment this fix is quite enough.

Introduction

Aseprite is an open source program to create animated sprites. Its main features are:

  • Sprites are composed by layers & frames (as separated concepts).
  • Supported color modes: RGBA, Indexed (palettes up to 256 colors), and Grayscale.
  • Load/save sequence of PNG files and GIF animations (also FLC, FLI, JPG, BMP, PCX, TGA).
  • Export/import animations to/from Sprite Sheets.
  • Tiled drawing mode, useful to draw patterns and textures.
  • Undo/Redo for every operation.
  • Mini-editor with real-time animation preview.
  • Multiple editors support.
  • Pixel art specific tools like filled Contour & Polygon.
  • Onion skinning
