This (deprecated) routine is used to set the transparency of widget borders. It is recommended that the developer instead just pass in a color with the correct transparency using IWidget_SetBorderColor
int IWidget_SetBorderTransparency(IWidget *pif, int pnTrans)
AEE_SUCCESS - The border transparency was successfully set AEE_EFAILED - The border transparency was not successfully set
On successful termination, the border transparency will be set to the provided value.
