v1.1

Changes since v1.0 in no particular order:

• Graphics:
  • The dependency to the plplot package has been removed --- easier installation and maintance, several (plplot) bugs cured
  • 3D support (SURFACE, SHADE_SURF and all T3D options for 2D plots) complete. Option TICK_GET added.
  • Plot positioning, labeling, character sizes etc... now identical to IDL
  • support for !C embedding command
  • ARROW, DEFROI
  • VELOVECT by @jtappin (replacement for VECTOR_FIELD)
• Widgets: too many improvements to be listed, but complicated widget interfaces like NASA's PLOTMAN or Aaron J. Barth's ATV are running just fine. Even xtetris works!
• Parallel processing with the support of IDL_IDLBridge:: commands
• SAVE/RESTORE of compiled procedures
• Shared memory mapping with SHMMAP and related commands
• Support of !NULL as a lefthand argument
• HDF5 improvements by @ogressel (write functions in particular)
• Better READ/WRITE of all graphic formats (GIF, JPEG, etc)
• New procedures and functions:
  • Eigenvalues and Eigenvectors: added ELMHES,HQR,TRIRED,LA_HELMES,LA_TRIRED,TRIQL
  • Sparse matrix: added SPRSIN,SPRSAB,SPRSAX,FULSTR,SPRSTP,LINBCG
  • GAUSSFIT, SCOPE_VARFETCH options, ARROW, DEFROI, option EDGE_CONSTANT for CONVOL
  • ALLANVAR, MEDABSDEV by @alaingdl
• Debug commands: .RET , .SO, .OUT, .SIZE
• IMPLIED_PRINT
• Speedup of many many functions and procedures (use of better algorithms and parallelism)
• OpenMP active on Apple silicon: GDL is very efficient now on OSX.
