12/14/18 Multithread processing for background filtering added to the Filter menu

12/14/18 XYpoints number drawing option and bitmap save button added to XYpoints dialog

12/12/18 Multithread processing for bandpass filtering added with a global switch checkbox  for future multithread processes set in the Option menu

12/11/18 First multithreaded process to take advantage of mult-core processors for conversion of 16 and 32 bit radargrams for most manufacturers (other than SEGY instruments) added to the Convert menu

12/8/18 GSSI multiplex 3d XY file imported and demultiplexed directly in the Create New Info survey listbox with either one or two channel separation as well

GPR-SLICE Library Update - February 13, 2019 - 748pm Pacific

note:   With multithreading one can speed up radargram signal processing, data conversion, gridding, time 0 editing, and slice binning data processing  by engaging this option and setting the number of logical cores desired to use in the Options menu.  For an average system with 4 or 8 logical cpu cores one can expect nearly 4-8  times speed in processing!     

note: Multithread processing requires the library update as well
