Shared graph nodes were incorrectly interpolated, only the first object with a shared graph node was interpolated properly.
Thanks to @Cooliokid956 for noticing that most of node types were **never** interpolated.
- Use a double hashmap to store interpolated data for each graph node and object. All translations, rotations and scales are now interpolated correctly.
- Add `GraphNodeScaleXYZ` type to scale to all 3 dimensions; Add `GEO_SCALE_XYZ` command.
gMtxTbl was also reaching it's limit, so dynamic allocation was added.
