- qt4->qt5 - in built qt5 6.1.5 because rhel7 is not upto date with qt5, removed findqwt.cmake - made a fix in qwt lib (qwt_plot_layout.h) to work with 5.15 and lower versions for qrect constr. - qt5 forms fixed, qt4 many hard coding forms switched to forms including qtabwidget, scrolls etc, fonts moved to forms - docking option enabled by default, removed option to disable docking feature from "Mode" - added qVersionResolve utility functions to handle compatibility before and after qt5.12 - qtplots (ian's code) takes in gain mode enable to set some settings within the class, with proper gain plot ticks - ensure gain plots have no zooming of z axis in 2d and y axis in 1d - removed placeholder text in qpalette in main window form as its not supportd until 5.12 (so using qt5.9 designer insted of qt5.15 to cope) - tab order Servers: - fixed some error messages that were empty for fail in funcs (mostly minor as if this error, major issues)

\fBQwtMatrixRasterData\fP implements an interface for a matrix of equidistant values, that can be used by a \fBQwtPlotRasterItem\fP\&. It implements a couple of resampling algorithms, to provide values for positions, that or not on the value matrix\&.

Assign the bounding interval for an axis\&. Setting the bounding intervals for the X/Y axis is mandatory to define the positions for the values of the value matrix\&. The interval in Z direction defines the possible range for the values in the matrix, what is f\&.e used by \fBQwtPlotSpectrogram\fP to map values to colors\&. The Z-interval might be the bounding interval of the values in the matrix, but usually it isn't\&. ( f\&.e a interval of 0\&.0-100\&.0 for values in percentage )
