can I use 4 feedback buffers (4 is hardware limit for transform feedback on my system) and additional buffers that do not use feedback in the same shader?

a) Can I use e.g. [jit.gl.tf 5 @shader tfsh] and connect 4 [jit.gl.buffer @type ... @outname ...] that use feedback and another [jit.gl.buffer @type .... ] without feedback? 

b) Can I use texelFetch in the jit.gl.tf shader targeting a buffer that is connected to the [jit.gl.mesh] ?

c) How to connect/access a texture in a jit.gl.tf shader?

Scope of the question is transform feedback patches that already use 4 buffers for feedback but which need additional information (not per vertex, but many) from outside to control the vertex program of the transform feedback shader. Using parameter arrays (

) is not feasible because I need several hundred values, which results in an error 

"Constant register limit exceeded at "parameter"; more than 1024 registers needed to compile program".

Hello,

hey Martin, please get in touch with me either privately or via the gl3 beta list with some patches describing what you are attempting. Most of these items sound like feature requests to me.
