The previous implementation seems to have been broken by Imgui updates.
There is also some improvement in focus handling and also a bug in
replace where the last match was not being replaced has been fixed.
Fixed also slowdown in large files when only one char was typed by not
searching until enter has been pressed.
Added key repetitions for enter and arrows to be able to handle large
number of matches and fixed some formatting problems.
After successfully finding matches and setting the cursor to them, the
screen would jump to the original window location upon closing the
window.
The error was caused by the wrong assumption that the scroll location
should be restored when window is closed. Instead, the right amount of
scrolling needs to be calculated to account for the window no longer
covering part of the text editor. Unused variable was discarded.
Another unrelated error is that the history of search names cannot be
accessed which will be addressed at a later PR.
Some issues related to the padding added to scroll past the end for
console that has padding added.
Added a shortcut to scroll editors one pixel at a time.
Fixed whole lines always drawn at the top even if scroll value is chosen
so that only a portion of the top line is visible. This caused errors in
horizontal scrolling.
Fixed Ctrl-F Ctrl-G and Ctrl-H messing the editor display.
Fixed the end of the line could not be clicked with mouse
Fixed line numbers and their lines could be displayed at different
heights.
Made numbers that represented lines floats instead of integers to allow
partial line display.
Two major improvements:
1) see through scrollbars when not hovered.
2) un-scrollable line numbers.
Also enlarged display region by eliminating padding. There is still a
problem with lines jumping when the scrollbar is dragged but it is
limited to one line and probably due to floating point error for scroll
bar number. It is much less noticeable than the previous jumping which
could involve several pages.

The top margin changes when popups block some portion on the screen.
Previously it was implemented adding blank lines at the bottom which
created problems if the windows was scrolled all the way to the bottom
and the popups were issued. The newer implementation doesn't use spaces
and simply resets the top of the window to be higher making the popup
interaction with the window more natural (no text disappears on the
lines the popup overlaps the text). changes can be identified form the
variables mTopMargin,mOldTopMargin and mNewTopMargin.
Unfortunately those changes revealed problems in cursor navigation that
needed to be addressed. Namely, the window will scroll up and down on
the line before last/second line at the top and similar problems for the
left and right. Those changes correspond to the function
EnsureCUrsorVisible()
Fixing those reveled yet more problems with scrolling past the end of
the file using the keyboard which required adding some more variables
and functions to support the correct handling, You find those changes in
the function MoveDown.
I also renamed some variables that had the wrong casing and fixed the
pasting but that is missing one line.
The reason for the error were the text preprocessor added to deal with
tabs was created to process entire files, not just lines or words. In
that context it cleaned trailing new lines if any existed but in the new
role that's not only unwanted but erroneous.
### Problem description
After that was fixed the console started to add two empty lines between
each output line. When splitting a string using new lines you need to
not add a new line to the last line created. Even if the text ends in an
end line, the split screen code is set to not discard empty lines.
### Implementation description
The fixes are straightforward.
I have implemented a fix that makes the scrollbars behave like they do
in VScode. Vertically you can scroll past the end of the file until only
the last line can be seen at the top. The horizontal bar behaves as if
every line was the same length which is the length of the longest line
in the file. Not only this creates a better user experience, but it also
fixes the annoying flicker that occurs when scrolling through large
files. Also, I have switched all the old draw calls to render text to
regular TextUnformatted calls which adds extra stability to the
resulting display.
To implement the behavior I added a dummy widget with the desired
dimensions.
This time it may be for good.
### Implementation description
As requested I added the preprocessing functionality into the pattern
editor. I had to duplicate a few functions and update the c++ library to
version 20. but now I can make sure the pattern editor doesn't see a tab
again. I also removed the preprocessor from where it was before because
it is not needed anymore. The changes were tested using a file that used
tabs for all its white space. The file was pasted into the pattern
editor and imported as well. I both cases no crashes occurred and the
files had no tabs on them.
Since the popup is fairly small I opted for a straight addition parallel
to the find/replace. To make code more clear the functions that create
each popup were coalesced and made their interface simpler. That forced
a reorganization of the data processing which translates to a larger
number of changes than usual. Most of those changes are just moving some
action from one function to another.
The old method to identify popups using the size and position of the
window was dropped in favor of one based on child windows and using
their names for a much easier and robust identification.
Added specialized functions to text editor to jump to a line or to given
coordinates with a simple interface that simplifies older code that
performed the same task.
Because this PR modifies heavily the same code as the previous PR (1983)
it is also included here to make merging easier.

Errors printed in the console can be clicked to have the cursor jump to
the source code line where the error is at.
The mouse cursor changes its shape to indicate which parts of the error
message can be clicked on the console. When the cursor jumps, the text
editor takes the focus away from the console and it scrolls the window
to make the line with the error is visible if it isn't. This code uses
the function created for the go-to PR but adds code to switch focus to
the target. When the codes are merged please keep both the part that
jumps the cursor and the part that sets the focus.

Some context menu entries that were available as shortcuts were greyed
out. This PR aims to fix them and improve how context menus work for the
text editor and the console. The improvements include:
- automatic focus on right click
- automatic selection on right click. If selected text is right-clicked
then copy, cut and find will use the selection, if no selection is
clicked but there is text were right-clicked, then the word will be
selected and used. If right-clicking empty space copy and cut will be
greyed out and find will start empty.
- similar functionality now exists for the console as well except the
menu has fewer options due to it being read-only.
- added esc to close console context menu
Even if focus is given to the pattern editor the cursor will not show
until the editor contains printable chars.
### Problem description
I was using the wrong condition to enter the loop that skipped the
default empty document.
### Implementation description
The fix was to check if there are lines of text that need to be
processed even if they are empty.
### Problem description
Previous implementation ignored everything after the first newline.
Other changes include:
- Added isEmpty() function that checks if editor has no content.
- replaced asserts with default behavior to avoid unneeded crashes.
- fixed off by one error in DeleteRange()
- some crashes occurred because readily available corrective actions
were not being taken. For example start/end being -1 in DeleteRange().
- At the heart of search/replace is the ability to translate from
indices into the text string to line/column coordinates used for
everything. To this end a function (StringIndexToCoordinates) was added
to do the translation taking utf-8 chars into account. This made the
recently added Utf8BytesToChars function unneeded, so it was removed.
- Removed commented out code that is not useful anymore. Also removed
tooltip code which is also unused.
- Removed unused parameter wrapAround to FindNext().
