There is no need to make genshader being generated by configure, anymore.
We used to use @srcdir@ but this was not embedded into Makefile.am. Hence,
we can avoid this and make it build normally.

The paths can be off when building out of tree, so have make put them in
for us instead. This requires turning the straight genshader.c file to a
template.

Besides the texture shader this also adds a second shader (def/default)
which is used to draw arbitrary colored vertices to the screen.

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.
