OK. This gets to the heart of issue T2. Insofar as all of the proposed
solutions:
- gdk-pixbuf
- ImageMagick or miniMagick
- a thin layer of our own
all rely on the same underlying libraries (libpng, libjpeg, etc.) that we'd
be using *anyways*, then it should be pretty easy to choose between them
according to the following criteria:
- which is someone willing to maintain?
- which has the best platform coverage?
- which bloats our binary the least?
- which is most efficient at run-time? (both speed and memory)
In particular, it sounds like we should focus on the exact APIs we'd be
using, and the code path that gets us in and out of the underlying libraries
as efficiently as possible.
