* geom
	* Primitives of dynamic runtime size (Eigen-like)
	* Tests
* phx
	* implement a 2D physics engine
* gfx
	* add more pixmap fonts
	* painter should be 2D only, make a separate 3D painter
	* implement proper .OBJ loader (with materials & vertex sharing)
	* deferred renderer
		* cascaded shadow maps
		* CPU frustum culling
		* solve banding issues
		* figure out better light volumes clipping
		* get rid of diffuse materials
		* find a better specular model (Blinn-Phong seems to over-shine the specular highlight)
		* optimize ssao: reconstruct position from depth buffer
		* more sophisticated objects inputs, support pre-made optimization structured
		* refactor:
			* remove copy-paste from shaders & rendering routine
			* split rendering into separate methods
* parser
	* overflow checks for number parsers
	* recursive parsers
* ui
	* elements reshape events (deal with lifetimes)
	* text layout in label with cached glyphs
	* grid layout element with equal cells
	* grid layout quadratic optimization
	* draggable window element
	* screen children sorting
	* slider element
