output: add shader support

To avoid the fixed function pipeline we should use shaders instead of
old glBegin/glEnd. This patch adds two basic shaders and functions that
load and initialize them.

To avoid loading the shaders at runtime we generate a source file which
contains them as strings so they are embedded in the binary.
