This function converts non-calibrated points to calibrated points.
VOID TouchPanelCalibrateAPoint( INT32 UncalX , INT32 UncalY , INT32 * pCalX , INT32 * pCalY );
Parameters
Remarks
A factor of 4 is hidden in the calculations of x and y. This provides sub-pixel accuracy to the GWES, which theoretically will improve accuracy if handwriting recognition is added to Windows CE. This value is not declared in a header file, so it agrees with the divisor used by the GWES in Touch.cpp.
The transform coefficients are already in vCalcParam.
