Getting __COLUMN__ of source code location.

[IchorDev]

I'm not aware of any way to do that exact thing. Measuring what 
column a line is on would be quite subjective. How wide is a tab 
space? Technically, it could be any number of columns depending 
on the display configuration used.

But you'd have to provide a unique ID manually anyway if, for 
instance, you create UI elements in a for loop:
```d
for(size_t i=0; i<10; i++){
	button();
}
```

I'd suggest using something more like Dear ImGui's ID system 
instead.
