@Skytrias [1/n] I haven't covered that yet (I will probably do it in the next part), but I control properties like size, colors, fonts, and some other things with stacks. So, for example, you might push a default size for each axis on the stack (as well as a default font, etc.), then...

@Skytrias [2/n] ...if you want to deviate a size, color, font, etc. for a button, you would just push a new value onto the associated stack before the button call, and then pop afterwards.

@Skytrias [3/n] I am really not that big of a "go nuts with C macros" guy, but there's one exception, and that's these widget property stacks. It all comes down to this:

#define DeferLoop(start, end) for(int _i_ = ((start), 0); _i_ == 0; _i_ += 1, (end))

@Skytrias [4/n] This is a utility that can "tag" a scope with an arbitrary `begin` and `end` expression. That's very useful for these scopes:

#define UI_PrefWidth(v) DeferLoop(UI_PushPrefWidth(v), UI_PopPrefWidth())

@Skytrias [5/5] This can then be used like so:

UI_PrefWidth(UI_Pixels(100, 1.0f)) UI_Button(...);
