This is a "minimal" example of a Vulkan app in Odin which renders a rainbow triangle.

The code in rainbow-triangle.odin can be compiled and ran from a terminal with the SINGLE command:

odin run rainbow-triangle.odin -file -o:speed

The code can be compiled and ran in debug mode with

odin run rainbow-triangle.odin -file -debug

which in particular (by default) prints out information throughout the setup process.
