Offline work done during weekend:

* handle fefuncR, fefuncG, fefuncB and fefuncA nodes
* implement fecomponenttransfer renderer
** identity and gamma modes render perfectly
** linear and table modes are rendering with very slight imperfections

This commit still mantains feComponentTransfer out of UI (still not implemented)
