[Lazarus] Memory leaks in AggPas

[Leonardo M. Ramé]

Hi, this is part of the dump generated by heaptrace from an fpGui
application that uses AggPAS (the AggPas code from fpGui is the
same as in Lazarus).

As you can see there are many leaks in agg_scanline_u and agg_array. 

Can anyone help me fixin this?.

822 unfreed memory blocks : 9873723
True heap size : 12550144
True free heap : 2543872
Should be : 2570832
