If this attempt fails, it's possible to set the +each screen of the system. Here is how that's done under the \ref osissues_x_scaling "X11" +and \ref osissues_windows_scaling "Windows" platforms. +If the resulting scale factor is not satisfactory, and also under the macOS platform, +it's possible to set the <tt>FLTK_SCALING_FACTOR</tt> environmental variable to the desired numerical value (e.g., 1.75) and any FLTK app will start scaled with that value.
