When I implemented the changes to allow creating breakpoints without
losing focus in the pattern editor and without forcing it to scroll to
the cursor position I broke the code that ensures the cursor is visible
after being moved to the source code that caused the error. All I needed
to do is to explicitly set the argument because the default is to not
scroll to the cursor when focus is given to the pattern editor
Editor was attempting to delete non-existent chars which is UB. Fixed by
checking before deleting. Also fixed was a problem created by having to
press enter to change the search string which advanced the selection to
the first match. In the next step one would expect that pressing enter
on the replace field would replace the selected item but was replacing
the item found after he first.
This was fixed by always replacing the current selection first. If the
replacement is the same as the searched term then replacing won't
advance the cursor, but if they are different then the current match
will no longer exist so it would search fora new one.
Attempt to fix WerWolv's strange off by one problem when using the
mouse. Added a popup question for files that contain long lines (>1024
bytes). Also improved the handling of large lines, so it won't stall the
app. May also contain other smaller issue fixes.
Fixed by only processing text that's visible.
Also fixed the cursor jumping to breakpoint line when selected by
clicking the line number and added highlighting of the current editing
line. An optimization that caches the number of utf-8 chars in each line
was included as well.
Finally, an error that caused ImHex to crash if a pattern was saved as
itself was also fixed.
