Extends append-editor-operation-menu-items so that when you
pass an editor and a position, it checks to see if that spot
has a non-string% snip and, if so, copies that one position
(or cuts it, depending).
Then, use that extension in DrRacket

The `scheme/base' module had become unreachable from the `mred' module.
While that normally would be a good thing, it lead to troublesome
multiple instantiations of `scheme/base' that caused problems for
attaching further modules to the namespace.
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.
If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces. For example, to see
per-line authors, use "git blame -w <file>". Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".

This restriction was enforced only for editors that have non
string-snip% snips. The restriction was in place because the
implementation strategy was to chain thru the snips in the editor
using (send snip next) and that isn't safe if the revision number
changes.
The lifting of the restriction is implemented by tracking the position
in the editor where the last snip ended and, if the revision number
changes, starting over trying to get a snip from that position. This
has the effect that, if the revision number never changes, the code
should behave the same as it was doing before (so hopefully any new
bugs I've introduced in this commit will only show up if the old
implementation would have raised an error)
Also, exploit the lifting of this restriction in the colorer so it
doesn't to restart the port during to coloring that happens along with
the parsing
Apologies for the gratuitious reindent, but I was having
a lot of trouble reading this file; it appears to have
last been worked on in an Emacs that used tabs for indentation
and doesn't use the same tab width as drracket.
A recent bug fix involved moving part of an `editor-canvas%' resize
out of atomic mode by queueing a callback (because the resize involves
quesrying the editor for its size, etc.), but then the callback
happens after a canvas is shown, which can cause it to appear with
bogus initial scrollbars. Queue the callback instead as a "refresh"
level callback, which gets a chance to run before a frame is made
visible.
The `on-size' method is called in atomic mode,
and we can't call into the editor's sizing functions
in atomic mode.
Watch out for refresh and/or window-sizing problems.
Cairo doesn't seem to deal correctly with an HDC produced
by BeginPaint() that has a clipping region. The problem affects
only Win64. Work around the problem by drawing to a separate
HDC and copying to/from the screen. (To see the problem before
this patch, draw the DrRacket window to the edge of the screen
and back, and observe tha the toolbar doesn't update correctly.)
This change could affect performance, but it should mostly
be limited to refresh when a window moves.
For a non-WXME file, fall back to the original load handler,
instead of re-implementing it. This makes module caching work
the right way. Falling back to the original means closing
the port and then re-opening the file to load, but that seems
ok.
This was broken in the class100 port. The init arguments
previously handled by the class100*/kw macro need to be
explicitly passed down.
Also, an (init-rest) is needed at the leaves of the class
hierarchy to ensure that internal super init args don't
leak via error messages. (the class100 macro always
inserts these)
Added a test file so similar breakage is detectable in the
future.
When the theme-specified default font has a localized name,
using it as a Pango faily name doesn't work, with the result that
text on controls could be truncated. Get a Pango-friendly
name by converting a LOGFONT to a Pango font description and
getting the name from the font description.
"My" -> "Racket". The "My" prefix was from initial experiments,
of course, and I just never got around to changing it before.
I think these names go into a global namespace, though, at the
ObjC level, so they need to have a distinct and Racket-specific
prefix.
