Only GDI drawing functions that return Boolean values can be accumulated in the current batch; calls to any other GDI functions immediately flush the current batch. Exceeding the batch limit or calling the GdiFlush function also flushes the current batch.
The batch limit is maintained for each thread separately. In order to completely disable batching, call GdiSetBatchLimit(1) during the initialization of each thread.
When started the Visual FoxPro 09.00.0000.5815 for Windows sets the batch limit to 20.
