Benjamin Otte 6a4bf2b993 gsk: Remove offset nodes
They were a neat idea while they lasted. But now, it's time for
categorized transform nodes, where matrices with
GSK_MATRIX_CATEGORY_2D_TRANSLATE are the exact replacement.

Renderers have not been adapted for this purpose, so they (continue to)
run slow paths.
