EuroSciPy 2014 sprint ideas

Priority

List of open bugs
List of pull requests -- many of these need only one or two minor updates in order to be merged!
The user manual can be vastly improved (see also #1012, #1043, ).
Add examples in docstrings (many functions are currently lacking examples in their docstrings)
The scikit-image logo doesn't currently have high contrast for color blind people. Find a color blind simulator and adjust the logo colors, or make an abstracted design.
Improve the website layout!
Change all imports from absolute to relative imports
In Contributor Guidelines, fix broken link to numpy documentation standard
Link to examples gallery from docstrings (will have to add special rst syntax: ..gallery: ...)

#931 -- finish scanline polygon drawing
Add drawing of text onto an image (skimage.draw)
Implement a better way of downsampling images (ask Stéfan)
Clean up growcut #736
Clean up dynamic time warping #518 (improve API, test)
We have several PRs left from a GSoC for image inpainting, but we need someone to review and integrate those.
Add IPython widgets for replicating skimage.viewer.canvastools

Add flag to normalize gradients in Canny edge detector so that the threshold values don't need to be adjusted as you change sigma
There's also an old list of requested features
Improve 3D support

Move and deprecate functions
- canny from filter to feature
- threshold_* from filter to exposure
Refactor canny detector so that we can use non-maximal filtering on its own (this would have been useful for teaching)
Add default structuring elements to morphology operations, and fall back on scipy.ndimage when parameters don't fit our optimized functions based on rank filters (2D images, bitdepth<12).
Fixes
- Fix watershed tie-breaking for boundaries (Issue 803)
- Update active image for skimage.viewer tools when a new image is opened (the displayed image changes, but the image used for filter doesn't currently change) (See mailing list)
- Fix blitting behavior for skimage.viewer. (PR #1030)
Improvements
- Add int64 support to our img_as_* functions
- Deprecate filter module and rename to filters or filtering (so we don't shadow the builtin filter)
- Distribute tifffile.py with scikit-image and make it the default for TIFF files
- Other IO improvements, such as reordering plugin preferences, issuing warnings when certain plugins are used that rescale the image to float, etc.
