glow buffer debug visualiser

pure script, there will be several of these using identical methodology for deferred. displays a given buffer via the
 texture[0] = "#glowbuffer"; entry,
passed along to a given shader via the
samplerNames[0] = "glowBuffer";entry
which corresponds to an expected variable name and register.

as much documentation for later as tool
