Fidgetty Widget System: Rewrite

[catswhiskers]

There is a package on void glfw-wayland-3.3.7_1. Presumably it would be ok to 
fiddle with staticglfw.nim and insert a preamble as in the in-house libui 
package vis:
    
    
    when defined(useLibUiDll):
      when defined(windows):
        const
          dllName* = "libui.dll"
      elif defined(macosx):
        const
          dllName* = "libui.dylib"
      else:
        const
          dllName* = "libui.so.0"
      {.pragma: mylib, dynlib: dllName.}
    else: ....
    
    
    Run

though obviously with a different library and define?
