Cosmetic changes
Always set rqTermAck to true after binding returns
Properly emit valueChanged in Rect setters
Add new shaders. Also output xxd'ed files to top dir.
Include vertex shader xxd's
Remove the remaining bits of deprecated GL usage

The drawing is now completely shader based, which makes away
with all usage of the depracted matrix stack. This also allows
us to do things like simple translations and texture coordinate
translation directly instead of doing everything indirectly
through matrices.

Fixed vertex attributes ('vertexPointer()' etc) are also
replaced with user defined attribute arrays.
