General
=======

GObjectifying and reference counting. Revisit misc XXX's and FIXME's in the 
code.

Canvas
======

- Background color.
- Idle thread that removes unneeded (fully white tiles)
- Networked tile manager (http, gnomevfs, or similar)
- Allow "exporting" the canvas through a webserver and simple javascript
  to act like a local maps.google.com for your sketchpad.
- Resolution independence.
- Integration with babl
- Allow querying of regions (or even tiles) with a specified non canvas
  native pixel format.
- Make png importing/exporting work on a tilerow by tilerow basis instead of requiring a buffer the size
  of the image.

Toolkit
=======

- Make the contents of views in the toolkit scale when the window is scaled.
- Add a higher quality blitter (resampling).
- OpenGL based blitting for desktop use

Misc
====

- Integrate the link list with the horizon class.

Tools
=====

- Couple tool_library with horizon class properly (or just integrate it)
- Add a writing tool (according to nomis' concept), that also accepts input
  from bluetooth keyboard (make bluetooth entry searchable,. and add
  simple HWR to entered text?)
