[matplotlib-devel] Upload a higher res logo to github

[Benjamin R. <ben...@ou...>]

Looks like github has changed the layout of the default landing page for
any github account.  This now has the account's profile image shown much
larger than originally intended.  Our front page now has a very pixelated
logo on display.  Given how much we pride ourselves on high-quality images,
we should probably fix this:
