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.
