d7f19ee610 Fix spelling in comments and documentation using codespell
Apply the utility from https://github.com/codespell-project/codespell/
to fix spelling issues in the headers under both include and interface
directories and add a file with a couple of exceptions.

The exact command line used was:

    $ codespell -w -I misc/scripts/codespell.ignore -i 3 in*

f5647828d0 Respect cell alignment when positioning the editors
Define the common logic for positioning editors not taking the entire
cell area (i.e. basically anything other than wxGridCellTextEditor) in
the new DoPositionEditor() function.

Also use the cell and editor alignment to decide where to position the
control if it's smaller than the cell, as it looks better if e.g.
wxGridCellDateEditor appears near the place where the date is displayed
instead of being centered in the middle of a wide column.

867cc2a3eb Handle clicks on grid edges normally when not using drag-resizing
Clicking on (or near) the grid column or row edges was handled specially
to allow dragging them in order to resize the column or row, but this
doesn't need to be done if drag-resizing the columns or rows is not
allowed in the first place and resulted in surprising user-visible
behaviour: e.g. when using row selection, clicking mostly anywhere in
the row selected it, except if the click happened to be between the two
columns, in which case it didn't.

Fix this and always select the row in such scenario now.

Unfortunately, doing this required adding yet more CanDragXXX()
functions in addition to the already impressive panoply of them in
wxGrid, but we need CanDragGridColEdges() as none of the existing
functions checked for m_useNativeHeader (there was instead an ad hoc
check for it directly in the mouse handling code) and the row version
had to be added for symmetry.

71d42a8290 Add wxGridCellRenderer::GetMaxBestSize()
This is another optimization, useful for the renderers that are used
with the values of a fixed form or part of a limited set, as it is much
faster to compute the best size for all values of the set rather than
computing them for all the cells in the column.

123e21c181 Refactor wxGrid::SetOrCalcColumnSizes() and SetOrCalcRowSizes()
Get rid of the unnecessarily complicated functions doing two quite
different things depending on whether their first boolean parameter was
true of false.

Instead, split their body between AutoSize{Columns,Rows}() (which used
to call them) and DoGetBestSize(), keeping just the part needed in each
case.

This is much simpler and even more efficient, as it avoids a completely
unnecessary call to CalcDimensions() and Refresh() from DoGetBestSize(),
which doesn't change the current size at all and so doesn't need to
refresh anything, but previously did it and not only once, but twice,
because both of SetOrCalc{Column,Row}Sizes() did it.

3307000baa Add wxGrid::GetSelectedRowBlocks() and GetSelectedColBlocks()
These functions are much simpler to use in the application code using
wxGrid in row- or column-only selection mode than GetSelectedBlocks()
itself because they take care of deduplicating, ordering and squashing
together the adjacent ranges, so that the application can use their
results directly, unlike with GetSelectedBlocks().

e6e6dbe077 Fix problems due to deleting grid cells in the event handlers
Deleting last grid rows or column in a few event handlers could result
in asserts/crashes in wxGrid code if the event handler also called
event.Skip(), as wxGrid still tried to perform the default action using
the deleted cell, when these events happened in the last row or column.

It's not totally clear whether calling event.Skip() after performing an
action modifying the grid should be allowed at all, but, in doubt, at
least avoid crashing if it does happen, by considering the event as
being handled (and even vetoed) if its handler deleted the cell in which
it was generated.

Closes #18731.

e5d03323f9 Rename wxGridBlockCoords::ContainsCell/Block() to just Contains()
These methods do the same thing, so it seems better to use the same name
for them.

This is not really a backwards-incompatible change, as these methods
were just added in the parent commit, so nobody is using them yet.

b8c3c60316 Allow extending selection using Shift-Page Up/Down keys
Also make Page Up/Down themselves work consistently with the other
cursor movement keys and clear current selection if they move the
cursor.

Even though DoMoveCursorByPage() is simpler than DoMoveCursorByBlock(),
still factor out AdvanceByPage() for consistency with AdvanceByBlock()
and because it still makes the code more clear.

bc3c6fea70 Fix Shift-Ctrl-arrows handling
Extending the selection with Ctrl-arrows is different from all the other
cases, as we need to combine both the selection anchor and the current
cell coordinates when doing it.

This means that we can't reuse the same PrepareForSelectionExpansion()
helper for this case, so this function is not useful finally and this
commit removes it entirely. It also replaces GetCurrentBlockCornerRow()
and GetCurrentBlockCornerCol() functions with GetExtensionAnchor() which
combines both of them.

Finally, it adds wxGridDirectionOperations::TryToAdvance() helper to
avoid repeating the IsAtBoundary() check which was previously part of
PrepareForSelectionExpansion() in multiple places.

And because the "extending" and normal parts of DoMoveCursorByBlock()
are so different now, it also factors out AdvanceByBlock() helper which
can be used to keep these parts well separate from each other instead of
intermixing them together.

With all these preparatory changes, it's finally possible to implement
the "extending selection by block" logic relatively easily, with the
bulk of this branch actually taken by comments explaining why do we have
to do what we do.

Add unit tests verifying that the functions used by Shift-Ctrl-arrow
work as expected.

30eaa28de5 Rename wxGrid::GetSelectionRange() to GetSelectedBlocks()
This seems to be more consistent with the existing functions and doesn't
create ambiguity with a grid range.

Also rename wxGridSelectionRange to just wxGridBlocks as, in principle,
this class could be used for iterating over any blocks, not just the
selected ones.

No changes in functionality, this is just a renaming.

69a05b0340 Use the same selection expansion logic for Shift-Ctrl-cursor
Expanding the selection from keyboard with Ctrl pressed should move in
the same way Ctrl-cursor does, but use the same selection anchor as
Shift-cursor does instead of always using the current cell.

This makes the expansion work much more intuitively in the grid, e.g.
pressing Shift-Ctrl-Down in

    1 2
    3 4

grid when 1 and 2 are selected now selects all the cells instead of
selecting 1 and 3 as it did before.

1d43ae7dc6 Refactor selection expansion code to use actual wxKeyboardState
Switch from using just "bool expandSelection" in the grid functions
(possibly) extending the current selection to using the full
wxKeyboardState.

This allows to pass it to ExtendOrCreateCurrentBlock() and slightly
simplify the code by using DoMoveCursorFromKeyboard().

791a9e68ae Rename and simplify wxGridBlockCoords::ContainsBlock()
Change the return type of this function to a simple and clear bool
instead of 3-valued int requiring a special explanation. This is simpler
and not any less efficient as checking for whether one block contains
another or the other one contains this one are separate operations
anyhow.

Rename the function to a more grammatically correct name.

Also move it inline as it's now trivial enough for this to be worth it.

0a5a904d8d Simplify wxGridSelectionRange to provide only iterators
This class was a strange hybrid of a container/view/range and iterator,
as it both provided begin()/end() container-like methods and
iterator-like methods for dereferencing/advancing.

Simplify this by removing the latter part and making this class really
just a range, with its own iterator class in order to avoid leaking the
exact type of the iterator used in the API.

Note that while it's now completely trivial, it is still useful as it
isolates the application code from the vector used to store the selected
blocks currently and will allow to change internal representation in the
future without breaking the existing code.

15b5a1865c Add a simple wxGrid::AssignTable() wrapper for SetTable()
In many case SetTable() is called with its takeOwnership parameter set
to true, as shown by the grid sample in which all 3 of the calls to
SetTable() set it to true, but calling it in this case is awkward, as
bare "true" in the caller is unreadable and almost invariably requires
an explanatory comment.

Improve the API by adding AssignTable(), which is the same to SetTable()
as the existing AssignImageList() to SetImageLabel(), which always takes
ownership of the table pointer.

8b2237cd2d Make row/column drag-resizing in wxGrid "live"
Update the column width immediately, as it's being dragged, instead of
drawing a temporary line showing the new column boundary using wxINVERT.

This results in better user experience, as it the effect of changing the
column width can be immediately seen (especially important for non-left
aligned columns or columns using ellipsizition) and, equally if not more
importantly, fixes wxGrid drag-resize not showing any visible UI at all
with wxGTK3 and wxOSX where wxINVERT is not implemented.

Don't reuse the same m_dragRowOrCol variable for both the index of the
row or column being drag-resized and for the index of the column being
drag-moved. Reusing it was confusing and made it more difficult what the
code was doing and what invariants were preserved in it, and just wasn't
worth saving a few bytes per wxGrid object.

This method is supposed to be overridden in the sub-windows of a
