+ling with affine matrices and 2D transformations. If you're writing a
+graphic library with 3D transformations, though, you are going to hit
+the jackpot: 4x4 matrices, projections, transformations, vectors, and
+quaternions.
+
+Most of this stuff exists, in various forms, in other libraries, but it
+has the major drawback of coming along with the rest of those libraries,
+which may or may not be what you want. Those libraries are also
+available in various languages, as long as those languages are C++;
+again, it may or may not be something you want.
+
+For this reason, I decided to write the thinnest, smallest possible
+layer needed to write a canvas library; given its relative size, and the
+propensity for graphics libraries to have a pun in their name, I decided
+to call it Graphene.
+
+This library provides types and their relative API; it does not deal
+with windowing system surfaces, drawing, scene graphs, or input. You're
+supposed to do that yourself, in your own canvas implementation, which
+is the whole point of writing the library in the first place.
