* #if > 0 -> dotjs
* more mappings, lv2 port props
* latency mechanism, see https://steinbergmedia.github.io/vst3_dev_portal/pages/Technical+Documentation/Workflow+Diagrams/Get+Latency+Call+Sequence.html, https://steinbergmedia.github.io/vst3_doc/vstinterfaces/classSteinberg_1_1Vst_1_1IAudioProcessor.html#af8884671ccefe68e0a86e72413a0fcf8, https://steinbergmedia.github.io/vst3_dev_portal/pages/Technical+Documentation/Workflow+Diagrams/Audio+Processor+Call+Sequence.html
* vst3 don't include/link libm if not needed, etc. (reduce to minimum reqs)
