| * Changes between 1.2 and 1.1: |
| * |
| * - the font pool is gone! All allocations are now performed |
| * with malloc() and free(). |
| * |
| * - introduced the FREE() macro and the Free() function for |
| * future use in destructors. |
| * |
| * - Init_FontPool() is now a macro to allow the compilation of |
| * 'legacy' applications (all four test programs have been updated). |
