Small update: v1.2.1 — IsoMetro Steam update #2523835

Optimized rendering for the bulldozer tool (previously, if you selected a large area with it, the way it would draw the overlay was super wasteful and would decimate the frame rate). Added additional vegetation assets, so undeveloped land is more visually interesting. Because of how the terrain system works, addition of the new vegetation assets means the placement of trees will look different when loading a save file, compared to how they looked when you saved it with prior game version, but it doesn't cause a meaningfully breaking change (the file should still load just fine, you just may notice the different tree placement which includes the new plants). Also added a version label to the main menu and pause menu.
