I'm using wxWidgets-3.0.0 with MinGW (tdm-gcc-4.8.1-3).
When building wxArt2D I get the following error.
C:\user_data\david\dajac\source_pool\wxArt2D\wxArt2D\packages\wxart2d\artbase\sr
c\drawer2d.cpp: In member function 'void a2dDrawer2D::FillPolygon(int,

To make the compiler happy, I changed the SortonXs() function to accept
void* parameters and explicitly cast to a2sAET** as follows.
static int SortonXs( const void* f, const void* s )
{
const a2dAET** first =(const a2dAET **)f;
const a2dAET** second =(const a2dAET **)s;
if ( ( *first )->m_xs < ( *second )->m_xs )
return -1;
else if ( ( *first )->m_xs > ( *second )->m_xs )
return 1;
return 0;
}
This hasn't been tested (beyond compiling) so I'm not sure it actually
gives the desired results. Beware if you have issues with filled polygons.
