* Changes in mcclim-0.9.9 relative to 0.9.8 Yule:

** [2024-09-03 Tue] Rewrite POINTER-DOCUMENTATION to fix performance issues

This involves better caching and more responsive handler when we wait for input.


** [2024-07-14 Sun] fix a memory leak in clx backend

** [2024-06-05 Wed] WITH-OUTPUT-TO-PIXMAP creates a pixmap with transparent background

It is not necessary to clean it anymore. MEDIUM-CLEAR-AREA handles now
transparency as expected too (i.e it uses :src operation instead of :over).

** [2024-06-04 Tue] ps/pdf backends use the correct transformation for text

** [2024-05-14 Tue] implement vertical text for backends using ttf renderer

This change also makes transform-glyphs work as specified in the specificaiton.

** [2024-03-24 Sun] allow selecting children of the presentation sequence

** [2024-03-24 Sun] bugfix: repaint scroll bars consistently

** [2024-02-13 Tue] Performance improvements for X11 text rendering

The untransformed text renders around 1.5x faster and the transformed text
renders around 400x faster.

** [2024-02-08 Thu] DRAW-TEXT implements now :TOWARD-POINT parameter

On top of the current device transformation, TOWARD-POINT specifies the text
direction.

A new demo interactive demo "Draw Text test" has been implemented that allows
experimentation with the text alignment, direction and transformations.

** [2024-02-19 Mon] UPDATING-OUTPUT does not overwrite CACHE-TEST when supplied

Previously when CACHE-VALUE was not supplied, then CACHE-TEST was set to
FORCE-UPDATE-CACHE-TEST, even when the programmer explicitly specified
:CACHE-TEST (CONSTANTLY T) ; from now on the CACHE-TEST is supplanted only when
neither CACHE-VALUE nor CACHE-TEST are supplied by the programmer.

** [2024-01-24 Wed] Change the class hierarchy of extended output streams

STANDARD-OUTPUT-RECORDING-STREAM is a superclass of
STANDARD-EXTENDED-OUTPUT-STREAM (previously it was the other way around).

** [2024-01-12 Fri] WITH-ROOM-FOR-GRAPHICS allows mixing text and graphics

Previously this operator was used to estabilish the transformation and local
coordinate system. These effects are achievable by using other operators.

From now on it works only on streams that maintain the text line and is used
strictly to incorporate graphics on the text line.

A new demo has been added that illustrates this new functionality.

** [2024-01-12 Fri] Rewrite STANDARD-TEXT-DISPLAYED-OUTPUT-RECORD to use DRAW-TEXT

This includes improving the implementation of the STANDARD-TEXT-CURSOR and
fixing bugs related to line breaks where the cursor did not change its size.

** [2024-01-12 Fri] Generalize the concept of a baseline for vertical directions

Additionally all output records may have a baseline, not only the text. That
will support future improvements to formatting operators.

** [2024-01-11 Thu] Implement the missing operator MAKE-DESIGN-FROM-OUTPUT-RECORD

This operator allows for incorporating graphical output records in drawing
functions.

** [2024-01-11 Thu] DRAW-TEXT is a subject of the medium transformation

Previously we've taken an interpretation that the argument :TRANSFORM-GLYPHS
decides whether the string is transformed or not; that interpretation was wrong
because this argument has a different purpose.

** [2024-01-06 Sat] Replaying the output does not change the stream's text cursor

The function REPLAY will save and restore the text cursor after execution.

** [2024-01-06 Sat] WITH-OUTPUT-TO-OUTPUT-RECORD does not terminate the current text line

For the extent of the macro body the text line is closed, but afterwards it is
reopened and the cursor position is re-set to the old position.

** [2024-01-06 Sat] Multi-directional pages for STANDARD-EXTENDED-OUTPUT-STREAM

It is now possible to specify the line and the page directions. Elements are
added piece-wise on the baseline that may be either vertical or horizontal.

#+begin_src lisp
  ;; New initargs (applies also to CLIM-STREAM-PANE as a subclass of SEOS):
  :line-direction [ :left-to-right :right-to-left :top-to-bottom :bottom-to-top ]
  :page-direction [ :top-to-bottom :bottom-to-top :left-to-right :right-to-left ]
#+end_src

Consequences are undefined when the line direction and the page direction are on
the same axis.

* Changes in mcclim-0.9.5 relative to 0.9.4:
** Installation: the systems clim-listener, clim-examples,
   and clouseau can now be loaded without loading the system mcclim
   first. Users with existing McCLIM installations should use the
   provided script:
                ./symlink-asd-files.sh /path/to/asdf-central-registry/
** New extension: tab-layout. This extension allows keeping a stack of panes
   whose foreground pane is controlled by a tab bar. This layout can be
   customized in backends and frame managers. For examples, see the
   gtkairo backend and the pixie frame manager.
** New extension function: SHEET-RGB-IMAGE: makes a screenshot of a sheet
   in the CLX backend. (Supported on truecolor visuals only for now.)
** New experimental extension: tree-with-cross-edges are an extension to
   the graph formatter.
** New experimental backend: clim-graphic-forms: native widgets on Windows.
   This backend is still very experimental (it doesn't run demos yet).
** New inspector feature: The inspector now displays more useful information
   about hash tables and generic functions.
** Specification compliance: Various layout panes no longer quite as
   aggressive at eating the space requirements of their children.
** Specification compliance: There is now a rudimentary implementation of
   NOTIFY-USER

** Improvement: the ACCEPTING-VALUES command table was renamed to
   ACCEPT-VALUES (as this is the name that the other clim-2 implementation
   uses)
** Improvement: the CLX backend should no longer cause focus stealing
   when an application has text-editor panes.  This change comes with
   a rudimentary click-to-focus-keyboard widget policy.
** Improvement: define-application-frame now allows a :default-initargs
   option. (This is not exactly a "specification compliance" fix, as
   d-a-frame is not defined to accept this option.).
** Improvement: menu-choose menus now look a little prettier.
** Improvement: added more styles for bordered-output: :rounded, :ellipse
** Improvement: Toggle button values now default to NIL.
** Improvement: Frame layouts are now inherited from the frame's
   superclass.
** Improvement: The Lisp Syntax is much improved: now recognizes
   delimiter characters, and more types of Lambda lists.
** Bug fix: Bezier designs should now draw in the right place in all
   backends.
** Bug fix: Text in Drei no longer "walks" to the left.
** Bug fix: Drei now has better support for delimiter gestures.
