## Regression Tests

### Manipulating mesh on failed load
- steps to reproduce
  - File, Open, choose a mesh file such as animal_bat.b3d
  - File, Open, choose a texture (purposely incorrect input)
- incorrect behaviors:
  - manipulating the loaded scene, such as calling remove()
  - SEGFAULT
- correct behaviors:
  - Do nothing to the current scene.
  - Show a message saying that the format is incorrect.


## What Qt Creator does
When building after clean, you can see the g++ commands in the "Compiler Output" bottom tab. See Debug and Release sections below.
