|
|
*
|
|
* 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).
