Symmetry/todo.txt

Todo:
	- Specific rendering mode for editor related rendering	
	- Editor modes for Transform, Rotate, Scale that operate similar to vim or blender.
	  Modes can be toggled by hotkeys and the operation will be applied to the selected object.
	  By default, we work on the ground axis i.e the xz plane and when we have alt pressed, we work in the vertical or y axis.
	- Add warning to genie build script when running on windows and WindowsSdkVersion cannot be found. This happens when the script is not run from vcvarsall command prompt
	- Improve README and add a screenshot to make the repository ready for making it public 
	- Refactor all global application state into 'Application_Context' struct. A single global instance of which is available everywhere

	- 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?
