Change the mouse cursor.
void pdfSetMouseCursor(PDFViewerHandle viewer, HCURSOR cursor)
This function changes the icon (an HCURSOR handle) used as the mouse pointer.

Note: calling pdfSetMouseCursor sets both the normal and link cursors, so make sure to call pdfSetMouseCursor first, and pdfSetMouseLinkCursor second. To set just the normal (non-link) cursor, first call pdfSetMouseCursor, then call pdfSetMouseLinkCursor with NULL.

pdfSetMouseCursor(viewer, LoadCursor(NULL, IDC_CROSS));
