genius-1.0.23-bp153.1.18

- Ensure neutrality of description, remove rhetoric questions from
  description. Update package summaries.

- Update to version 1.0.23:
  + Stop depending the build system on gnome-common.
  + Help is now built as HTML and displayed in the browser,meaning
    it actually works, links work, and it doesn't depend on any
    particular desktop environment being installed. The HTML help
    is also shown in the command line version when "manual" is run.
  + New example for Duffing equation.
  + New example on traces of the Peano function.
  + Couple of fixes/improvements in the examples.
  + Fix a crash on SurfacePlotDrawLines/Points.
  + Updated translations.
- Drop some %dir and %doc: no longer needed.

- Replace scrollkeeper with rarian-scrollkeeper-compat
  BuildRequires: scollkeeper is dead, let's at least use the proper
  replacement.

- Update to version 1.0.22:
  + Add a line plot version of the heat equation FDM animation.
    example, and improve the surface plot version.
  + Add argument principle example.
  + Add two Mandelbrot set examples and a Newton's fractal example.
  + Add examples for visualizing complex mappings.
  + Add example vizualizations for Riemann and Darboux sums.
  + Split the examples into submenus as there is now too many of
    them.
  + Add "filled" property to lines to allow drawing filled
    polygons.
  + Add LinePlotWaitForClick and LinePlotMouseLocation functions
    for interactive programs (used for some of the above new
    examples).
  + LinePlotDrawPoints and LinePlotDrawLine accept a column vector
    of complex nubmers.
  + Fix possible infinite loop on parse on systems with newer flex.
  + Fix setting of elements in transposed matrices (vectors).
  + Fix doc string to ErrorFunction.
  + Fix bad behavour upon double hitting "Run".
  + Fix vte deprecations, require 0.26 now.
  + Fix some strings and fixes to documentation.
  + Fix segfault when trying to swap a protected id with swapwith.
  + Fix StripZeroColumns behavior on a zero matrix.
  + Fix Subfactorial, and let Subfactorial, Factorial,
    DoubleFactorial apply over matrix.
  + Fix some inverse trig functions with complex arguments.
  + Other minor fixes including some crashes.

- Update to version 1.0.21:
  + Add vibrating drumhead modes example, heat equation with
    explicit FDM, improve the Laplace FDM example.
  + Fix output of chopped floating point numbers, especially
    chopped imaginary parts.
  + Fix output of results as floats in pretty print.
  + Fix SurfacePlotVariableNames to redraw when changing variable
    names.
  + Updated translations.

- Update to version 1.0.20:
  + Add more sizes of icons including SVG, and add Keywords to the
    .desktop file.
  + Documentation updates.
  + Fix PeriodicExtension function.
  + ErrorFunction (erf) is using MPFR for real values so it is far
    more precise and faster.
  + The Fourier series example is no longer using a hand coded
    graph and hand computed series, so it can now be easily
    modified to show series for different functions.
  + Fix GCC 5 compilation.
  + A couple of minor fixes in the plotting code including one
    possible crasher.
  + Updated translations.

- Update to version 1.0.19:
  + New menu: Examples. These are annotated programs that show some
    mathematical concept. Generally taken from the classes I have
    been teaching. They are installed under
    prefix/share/genius/examples/ and are mostly using graphics so
    only work in the graphical GNOME/GTK version
  + New plotting functions: SurfacePlotDrawLine,
    SurfacePlotDrawPoints, SurfacePlotClear, PlotWindowPresent.
  + New rotation animation in the surface plot window.
  + Fix string constants from compiled library starting with 'E'.
  + A few fixes.
  + Updated translations.

- Update to version 1.0.18:
  + New general functions: KroneckerProduct (alias TensorProduct),
    NewtonsMethod, HalleysMethod, LambertW, LambertWm1,
    NonzeroColumns, NonzeroElements, DisplayVariables, PrintTable,
    SetElement, SetVElement.
  + New plotting functions: PlotCanvasFreeze/PlotCanvasThaw to
    improve flicker if doing animations with genius, and
    LinePlotDrawPoints function to draw just points without the
    line. While plotting errors are no longer forced into a dialog,
    and presence of errors is indicated in the graph window below
    the graph.
  + Allow setting color in LinePlotDrawLine with RGB vector. When
    the vector building notation is done with floats and the final
    number is within 2^-20 times the step size of the goal, assume
    there were roundoff errors and still add it, just like for
    loops, so something like 1.0:0.1:3.0 now works.
  + Implement subsecond precision in wait function.
  + Fix memory corruption error triggered in nested floating point
    for loops with a floating point step.
  + Few minor bug fixes and fix some more compile warnings in
    gtkextra.
  + Streamline the compiled file format (saves about 30kb).
  + A few improvements to the documentation.
  + Updated translations.

- Update to version 1.0.17:
  + Better precision for graphs especially when zoomed it a lot,
    and make font smaller if needed.
  + Line plots and parametric plots now allow "fit dependent axis"
    automatically when y limits are unspecified. And this is the
    default in the UI.
  + Add export of graphs to PDF directly.
  + Line plot step size is adaptive, also line plots now detect
    jumps and do not draw a connecting line, try plotting UnitStep
    for example.
  + Use arrow keys to move around a line plot.
  + left-right arrow keys rotate surface plot.
  + All plots are now antialiased on the screen (due to GtkExtra
    update and cairo usage).
  + Update internal GtkExtra to 3.0.5, and forward port all our
    changes/fixes (this gets us closer to supporting GTK+3 at some
    point).
  + Completion for "help on function" in the GUI.
  + Fix FindRootBisection and FindRootMullersMethod.
  + Factors is now a lot faster on very large numbers (as fast as
    Factorize).
  + Fix placement of labels on surface plots.
  + A few small fixes and updates to the documentation.
  + A few minor bugfixes.
  + Update mersenne primes (new one is known).
  + Updated translations.

- Update to version 1.0.16:
  + Add SurfacePlotData and SurfacePlotDataGrid functions to draw
    arbitrary surface data, to allow more complicated 3d plots and
    3d plots from data.
  + Add LinePlotDrawAxisLabels and SurfacePlotDrawLegends
    parameters and add corresponding UI checkboxes
  + Add ExportPlot function to export the current contents of the
    plot window to a file from GEL
  + Surface plot now allows "fit dependent axis" automatically when
    z limits are unspecified.  And this is the default in the UI
  + Add sinc, BesselJ0, BesselJ1, BesselJn, BesselY0, BesselY1,
    BesselYn functions
  + Plot window slightly bigger (700x500 now) and there are wider
    side margins in the lineplot (2D) version to make tick labels
    always fit.
  + In both 2D and 3D plots, tick labels now use scientific
    notation when needed to avoid ugly labels
  + In surface plot the gradient always shows only the range of the
    function, so color is more useful when zoomed out.
  + Simpler output when typing "help foo" when foo is neither
    defined nor documented.
  + When for/sum/prod loops are in terms of floating point numbers
    and the final number is within 2^-20 times the step size of the
    goal, assume there were roundoff errors and still execute the
    body
  + Handle wider matrices than 2^15 columns in expansion
  + Fix flicker when plotting surfaces to allow animations with 3d
    plots
  + Fix possible uninitialized crash when reading badly formed
    standard library (should never happen, but ...)
  + Fix LinearRecursiveSequence and allow it to take vector for n
  + Fix crash on uninitialized variables in conjugate transpose
  + Fix crash on extreme zoom out or zoom in of a graph
  + Fix derivatives of Im and Re
  + Fix file chooser dialogs not starting in current directory
  + Avoid double error about uninitialized variables
  + Spelling fixes and documentation fixes
  + Require MPFR at least 2.3.0
  + Updated translations.

- Update to version 1.0.15:
  + New functions CurrentTime, MacaulayRep, MacaulayLowerOperator,
    MacaulayBound.
  + Fix rational powers of negative numbers, and exact negative
    rational powers.
  + Fix zooming in graphs using the mouse when the functions take
    long to run.
  + Accept log instead of ln for symbolic derivative when used with
    only one parameter.
  + Updated translations.

- Add explicit shared-mime-info BuildRequires since we use the
  %mime_database_* macros.

- Update to version 1.0.14:
  + Fix some compilation warnings
  + Fix a crasher
  + Optimize and quantize the new pngs for a smaller file
  + Updated translations.
- Drop genius-fix-warnings.patch: fixed upstream.

- Update to version 1.0.13:
  + Add ShuffleVector
  + Add increment and swapwith operators
  + Require gtk 2.18 and fix up some deprecated function usage
  + Slightly more cache friendly matrix traversal
  + Optimize Combinations, Permutations, SortVector,
    IntegerQuotient
  + Lots of tiny random optimizations
  + Open help even if the URI api is broken
  + Make pngs in the distribution smaller yet
  + Make the compiled library slightly smaller
  + Some more vector functions accept null properly
  + Minor portability fixes
  + Updated translations.
- Add gnome-doc-utils-devel BuildRequires for new dependency.
- Add genius-fix-warnings.patch: fix build warnings that make the
  build fail.

- Move to pkgconfig()-style BuildRequires:
  + Old ones: gtk2-devel, gtksourceview-devel, vte-devel.
  + New ones: glib-2.0, gtk+-2.0, gtksourceview-2.0, vte.

- Added support for translation-update-upstream.

- Call relevant macros in %post/%postun:
  + %desktop_database_post/postun because the package ships at
    least one desktop file.
  + %icon_theme_cache_post/postun because the package ships themed
    icons.
  + %mime_database_post/postun because the package ships a mime
    type definition.
- Pass %{?no_lang_C} to %find_lang so that english documentation
  can be packaged with the program, and not in the lang subpackage.
- Change Requires of lang subpackage to Recommends, since the
  english documentation is not there anymore.
- Remove shared-mime-info Requires: if it's not there, then we
  simply don't need to update the mime database.

- Update to version 1.0.12:
  + Recently used files menu
  + Only run ps2epsi on eps output if selected, it can be very slow
    and I've realized it's not commonly needed

    the IDE
  + Fix handling of newlines in the lexer
  + Fix CrossProduct
  + Some self tests were missing in the distro

  remove the autoreconf call in build.

- Add genius-make382.patch: Fix build with make 3.82
- Add autoreconf call in build section.

- Update to version 1.0.11:
  + Build fix for some versions of ncurses
  + Minor documentation updates.
