We'd like to use a consistent checksum scheme everywhere so that we can:
a) incorporate archive checksums into our specs and have a
consistent hashing algorithm across all specs.
b) index mirrors with a consistent type of checksum, and not one that
is dependent on how spack packages are written.
- [x] convert existing md5, sha224, sha512, sha1 checksums to sha256

"""PNGwriter is a very easy to use open source graphics library that uses

PNG as its output format. The interface has been designed to be as simple

RGB (red, green, blue), HSV (hue, saturation, value/brightness) and CMYK
|
|
(cyan, magenta, yellow, black) colour spaces, basic shapes, scaling,
|

bilinear interpolation, full TrueType antialiased and rotated text support,

bezier curves, opening existing PNG images and more.
