	- Necessary basic editor additions like placing objects, scaling, rotating etc
	- Add fallback shader
	- Implement Game States
	- Store Materials in new format supported by parser
	- Add model description file which has the same syntax supported by parser and modify old blender exporter to conform to new standards
	- Fix bugs with sound sources not updating
	- Add creating distributable build and uploading to itch.io account support to GENie under windows and linux.
	- Remove hardcoded numerical values from sscanf and other format strings.
	? Recalculated bounding boxes for rotated meshes
	? Wrap malloc and free calls in custom functions to track usage
	? File extension checking for asset loading
	? Only allocate hashmap bucket when required
	- Mapping actions to keybindings, for example map action "Jump" to Space key etc
	? Add marking or queuing up custom meshes for debug render with particular transform and color for rendering bounding spheres for example
	? Interleaved vbos for meshes and changes to blender exporter accordingly
	- Enumerate and save all the uniform and attribute positions in shader when it is added and cache them in shader object?
	? Better handling incase assets folder is not found
	- Write entity to/from file
	- Ogg format loading and playback
	- Sound streaming
	- Implment missing sound source properties (inner/outer cone, getting sound source data)
	- Shadow maps
	- Print processor stats and machine capabilites RAM etc on every run to log.
	- Do input maps really need to be queried by their string names?
	- Write default config/keybindings etc to file if none are found in preferences dir
	- Multisampled textures and framebuffers
	- Validate necessary assets at game launch
	- Gamma correctness
	- Log and debug/stats output in gui
	- Event Subsystem
	- Textual/Binary format for data serialization and persistance
	- Array based string type comptible with cstring(char*)
	- ???
	- Profit!

Improvements:
	- Better naming semantics for examples, init/deinit for initialization and cleanup and create/destroy when memory is allocated or deallocated


Bugs:
	- Better handling of wav format checking at load time
	- Fix light rotation/direction bugs
	- Fix lights type not being correctly saved/loaded from file
	- Fix mouse button press/release behaviour by investigating how sdl handles mouse release or by explicitly caching mouse state by using event callbacks recieved when a mousebutton release event is reported by sdl
