/**
|
|
* @brief Implement a very basic GAL used to draw, plot and convert texts in segments
|
|
* for DRC functions, using the common GAL functions.
|
|
* Draw functions use wxDC.
|
|
* Plot functions use a PLOTTER
|
|
* Convert texts in segments use a callback function created by the caller
|
|
* @file basic_gal.cpp
