Maintains the old and new code-paths:
- if the shader was made with explicit filteroptions, use those
- if not, infer the filteroptions from the filterquality enum
(and the legacy heuristics of sniffing/snapping the ctm)
In either case, the bulk of the onProgram() is shared, driving off
the (possibly computed locally) filteroptions.
bench looks sort like we expect:
509.28 filteroptions_sampling_0_mipmap_0 8888
495.76 filteroptions_sampling_0_mipmap_1 8888
642.52 filteroptions_sampling_0_mipmap_2 8888
942.40 filteroptions_sampling_1_mipmap_0 8888
976.94 filteroptions_sampling_1_mipmap_1 8888
1686.34 filteroptions_sampling_1_mipmap_2 8888
