Albrecht Schlosser 8d940f3581 Put fix for issue #1214 (Windows "solid lines") under ABI guards
Original issue title:
  "Windows: dotted lines may be drawn solid when GUI is rescaled"

Unfortunately commit 880636eb12 broke
  the ABI because it added a variable to a public header. This commit
  uses ABI guards '#if FL_ABI_VERSION >= 10403" for the same fix.

Note: The full fix w/o ABI guards is already available in FLTK 1.5.

README - Fast Light Tool Kit (FLTK) Version 1.4.3

WHAT IS FLTK?

The Fast Light Tool Kit is a cross-platform C++ GUI toolkit for
UNIX®/Linux® (X11 or Wayland), Microsoft® Windows®, and macOS®.
FLTK provides modern GUI functionality without bloat and
supports 3D graphics via OpenGL® and its built-in GLUT
emulation. It was originally developed by Mr. Bill Spitzak
and is currently maintained by a small group of developers
across the world with a central repository on GitHub.
