Use Java exception or Vulkan error code in high-level command wrappers?

[chuigda]

Java exception

• Pros
  • More Java
  • Useful when you want to handle bunch of exceptions all at once
  • User doesn't have to check command by command
• Cons
  • Less "exact" mapping between Java and Vulkan
  • Increased code generation complexity
  • Bad when you want to handle exception one by one, or deliberately ignore some exceptions

LWJGL uses vulkan error code and that should be meaningful somehow. We just follow them.
