442	Updated plotting package, hbackground.F	arango	arango	"Updated file '''hbackground.F''' for ROMS plotting package to add the new changes for common block '''mapcm1''' in the NCAR's library version 5.2.0. I can believe that they continue making changes to this common block once in a while. It is annoying because the library is not backward compatible.

A new cpp option '''NCARG520''' is introduced in the '''makefile''' to allow compiling with this version of the library.

Many thanks to Simon Spagnol for [https://www.myroms.org/forum/viewtopic.php?f=23&t=1924 providing us] his updated '''hbackground.F''' for this new version of the libray.

I am also using the logical flag '''lmask''' in '''mskcle.F''' to avoid land/sea masking, if wanted, when '''lmask=0''' even if there is a land/sea masking array in the input NetCDF.  In this way, the user may utilize this standard input parameter for land/sea masking behaviors in the plot. This is useful when plotting the raw bathymetry with the '''gebco''' palettes. It allows to color land with the appropriate values of the topography. The '''lmask=1''' paints the land with a solid color.  Of course, the '''hraw''' variable, record 1, needs to have positive values in the land and negative values in the water.  Recall that the bathymetry used in ROMS, variable '''h''', has the water values positive and the land is cropped to a constant positive value greater than zero. The variable '''hraw''' is never used in ROMS. Many users ignore this variable.  I always like to write in record 1, the original topography before cropping and smoothing. In this way we save the starting raw topography for future reference."	upgrade	closed	major	Plotting Package	Plotting	3.4	Done
