just remove it.

Reimplement wxPathOnly() using wxFileName::GetPath()

Add tests checking that the function still performs as before and
document that its behaviour slightly differs from GetPath().

Log Message:
-----------
Validate decoded pixel indices in wxGIFDecoder::ConvertToImage()

Avoid reading uninitialized memory if any of the pixels in the input
data reference entries beyond the end of the palette.

Closes #26521.

Avoid writing beyond the buffer end for GIFs with zero size

Reject GIF frames with zero width or height to avoid writing beyond the
(empty) buffer returned by malloc(0).

Closes #26524.

Log Message:
-----------
Fix buffer overflow in wxVsnprintf() when size==0

Don't write NUL byte to "buf[size - 1]" when size is 0.

This bug was present in both implementations of wxVsnprintf(), so fix it
in both places too.

Closes #26522.

Log Message:
-----------
Fix palette buffer overflow in wxGIFHandler::SaveFile()

The image palette can have more than the 256 entries a GIF supports, for
example when the image was loaded from an XPM that declares a larger
colour count. wxGIFHandler_GetPalette(), called when saving a GIF,
copied every entry into the caller's fixed wxRGB pal[256] buffer,
overflowing it.

Such an image can't be represented as a GIF, so reject the save with an
error message instead of overflowing the buffer or writing out a silently
truncated palette.

Closes #26532.

Merge branch 'reimplement-pathonly'

This incidentally fixes a buffer overflow in this function, see #26526.

See #26537.
