Application Event System Discussion

[AlexvZyl]

We need to implement a better way of handling events in Lumen and this is going to tie in directly with #98.

The methodology of how we do it now is good, instead of immediately calling functions that handle events (and blocking the application) we set flags (and populate structs with data regarding the latest instance of the event) and then handle them once per frame. This also prevents us from handling events more than we need to.

This is going to includes things such as:

• Mouse inputs
• Key inputs
• File events (Loading & saving)
• File drop event
• Window close
• Resize event
• Window Focus (and de-focus)

I think it would be a good idea for each window to have its own event callback/queue/buffer/states, depending on how we decide on implementing events.
