ADD: [block] Try automatically placing labels
FIX: [contour] errors in unit tests
ADDED: [signalling] Dividers should have centerlines
FIXED: [signalling] vertical pointer <- at A+; should point backwards.
FIX: [block] content below a label should observe margin
FIXED: Behaviour is different for "\c(red)A\c()B" is different from "\mn(30)A\mn()B". 
       In most label processing code we call StringFormat::Apply() then StringFormat::ExpandReferences(). 
       The first call will find 'red' invalid (no color set is provided to 'Apply'), so text color remains
       black in default (and 'B' will be black). In contrast, text size is set to 30 in 'Apply' and then 
       'ExpandReferences' will use it also for 'B'.

In 8.6.2

In 8.5
ADDED: [win] Added the ability to work with alt-text embedded charts to the MFC GUI.
ADDED: [win] Added Auto Save and Instant compilation options to the MFC GUI. Selecting them will save the chart and/or automatically compile it after every change.
FIXED: [mac] Fixed alt-text embedding (clipboard stopped working). This was due to the use of APIs deprecated in MacOS 10.11 (Big Sur). Now this is the minimum version required for Msc-generator to run on the Mac.

FIXED: charts containing the text @samp{cid} had empty alt-text in PowerPoint when alt-text embedded (Word works fine, no clue why). A non-backwards compatible fix is provided (Thanks Attila, 8.4)
CHANGED: Completely rewritten tokenizing for all languages. Instead of flex, the tokenizer of maphoon is used (by Hans de Nivelle), allowing the removal of many quite outdated constructs from the code. Also, parsing speed has increased by 10%, especially useful for coloring. (8.4)

In 8.3
CANCELLED: signalling: parsing not to require a ; after every }. Update doc, too.
           (Boxes and pipes would need a semicolon as we could not decide based on a single lookahead
            token if a pipe segment comes or something else. That is, if an entity name comes it can either
            be a new box/pipe segment or anything else, such as an arrow. Thus to remain LR(1), we skip this.)
CHANGED: [graph] The default filename extension for graphs is @samp{gv}, as decided by the graphviz community @url{https://marc.info/?l=graphviz-devel&m=129418103126092}.

DOCED: hspace left comment
ADDED: all: define and use empty styles all you like

ADDED: gui: Rename Entity


In 6.3.8

FIXED: color=xx attribute not recognized for subsequent pipes
ADDED: Color to recognize #010203 rgb spec
ADDED: mscgen color names (W3C color names indeed)
ADDED: Text background color
ADDED: alternative forms of attribute names
ADDED: style to apply to arrows starting from an entity, but not blockarrows
ADDED: Arrows to actually take the atext aline and arrow attribute of the src entity
ADDED: Global attribute for arcgradient
ADDED: Wordwraparcs & word wrapping defaults
ADDED: hscale different handling and width
ADDED: mscgen design
CANCELLED: color and arrowhead attributes to arrow refinement styles
ADDED: Handling of -x ->* --,==,::,.. arrow symbols in compatibility mode

DOCED: new arrow symbol (==> and =>>)
DOCED: new entity attributes (atext, aline, arrow)
DOCED: exactly how multisegment style is calculated
DOCED: skipType
DOCED: Mscgen backwards compatibility

This is how it works.
- Three modes: signalling, signalling-warning (for mscgen constructs) and
  mscgen compat mode
- All non conflicting mscgen attributes and arrow symbols and accepted in all modes
  but they give warning in signalling-warning mode
	- textbkcolor on empty boxes -> fill.color
	- wordwraparcs -> arrow.text.word_wrap = yes
	- arcskip -> slant_depth
	- arcgradient is translated to a degree -> angle (gives warning with hscale=auto)
	- line breaks in quoted text (not accepted in Msc-generator)
- Conflicting constructs are as follows
   - -x and ->*: these are interpreted differently in the signalling and mscgen modes
   - :> and :: exist only in mscgen mode
   - hscale value interpreted differently in mscgen mode
   - style of arrows is different under mscgen mode
   - word wrapping is enabled for mscgen defined boxes in mscgen mode
   - -- and == are arrows in mscgen
Special features to cater for in both modes
- text.bkcolor (no warning)
- ||| (no warning)
- Tpdf (no warning)
- aline.*, atext.*, arrow.* on entities to influence arrows starting
  from this entity (no warning)
- width (besides warning, it is used only at file output/export, if command line does not override it
