Text is athe biggest bottleneck right now. Raylib as a renderer fails for this prototype in that front.
I'll eventually need to look into other solutions such as SDL2 + something that renders UI boxes & text very fast...
Saw that layout really should be separated from the style struct, so went ahead and pulled the trigger...
A bunch of other refactors have also been done
* Lifted layout out of style, its not separate in UI_Box and in UI_State there is not a UI_LayoutCombo stack.
* UI_StyleTheme renamed to UI_StyleCombo
* UI_Theme has both UI_StyleCombo & UI_LayoutCombo
* Made files for the "project" related code
* ui_layout_compute moved to its own file, ui_layout now used for layout related data structures and interfacing
* Impovements to horizontal & vertical box impl
* UI_Box now keeps track of how many ancestors it has
Renamed HashTable to HMapZPL, with procs having the zpl_ namespace prefix.
(I want to eventually get away from using it)
Started to use the grime pattern for library aliasing better.
I originally wanted to reference Ryan's UI series along with the RAD Debugger codebase, but that ended up being too convoluted of a route. Instead, I moved on to just doing a deep dive on imgui content I could find to learn from and associated libraries available. I collected my notes so far in this repo [IMGUI_Notes](https://github.com/Ed94/IMGUI_Notes).
For now I have the base scaffolding datatype wise for the prototype ui.
There is now a 2D camera in the workspace!
We have a basic 'Frame' definition. It doesn't have any interaction yet...
I started to define spacial math, mostly for doing conversion and getting a grounding on pixel/points/cm reference. The world space is in cm.
