This commit has Fl_Cairo_Graphics_Driver compute string widths in 2 ways:
1) when the string contains several unicode characters, the width of the
whole string is computed, accounting for kerning when it occurs;
2) when the string contains a single unicode character, its width is
computed, memorised, and re-used next time it's necessary.
The effect of this approach is
- Fl_Text_Display is fast because it uses memorised single character widths repeatedly
- Fl_Input is drawn accurately because the cursor position is determined
by string widths, not by sums of character widths.

... if GDIPLUS is disabled.
Thanks to Winfried Szukalski for reporting this.

The "choice arrow" used two "down-arrows" which was different than
all the other schemes. Changed to up-arrow and down-arrow to make
this more consistent.
The exception is the default scheme (none or base) which uses only
one down-arrow.

The Page_Format and Page_Layout enums have been conceived for them to be combinable
into a single int value.

Menu windows containing sub-menus are now processed differently.
|
|
This commit uses Wayland popup positionning methods to handle common
menu windows and prevents them from expanding below display bottom or above top.
The previous algorithm remains in place for menu windows higher than
the display height. Further changes for these big menus may come later.

This commit should fix: once the mouse leaves the app window area and returns back to it
(app loses focus and gets it again) the crash happens.

- remove static variable 'string_count'
- improve and document methods debug() and hexdump()
This commit does not resolve issue 601 but removes some development
leftovers.
Methods debug() and hexdump() left for debugging as requested.

The driver's clip_ member was not updated to the new Cairo clip state
which rendered function Fl_Cairo_Graphics_Driver::clip_box() inaccurate.

It may be useful to some to have the terminal emit an error character
to show unknown escape sequences. Off by default, unknown escape sequences
are silently ignored. If enabled, '¿' is inserted instead.

This is basically a rewrite of the ESC handler, keeping state
in the class, so ESC sequences can continued between called
to append() (such as when reading data from a pipe in blocks).
New private class 'Fl_Escape_Seq' handles parsing and state info.
It also has careful bounds checking during parsing.
Backspace supports Unicode, and the unicode chars can straddle
across append() operations as well.
Private variables in Fl_Simple_Terminal renamed _xxx to xxx_
to improve CMP compliance.

SVG is now decompressed in memory
Bitmap invalid array length handling to return an error
RGB Image data reader to return error if image data is too short
FLUID: Add size argument to bitmap and JPEG data

This addresses a comment from MoAlyousef in issue #577
on 12/15/2022 requesting backspace processing.

Also add Fl::option(OPTION_FNFC_USES_ZENITY)
|
|
If available, it is used on Linux regardless of the current desktop because
it offers free XDG portal integration, which means it picks the correct file
chooser on all desktops, and allows for meaningful file selection in sandbox
environments like Flatpak.

Change some method names to comply with FLTK style as discussed
in fltk.coredev, thread "Fl_Flex method name question".
* Rename Fl_Flex::margins(...) to Fl_Flex::margin(...)
(use singular form for all margin related methods)
* Remove Fl_Flex::setSize() and isSetSize() "backwards compatibility" methods
* Rename Fl_Flex::set_size(...) to fixed(...)
Note: the latter affects existing (pre-release) fluid (.fl) files: you may
want to edit and replace "set_size_tuples" with "fixed_size_tuples"

@wcout reports that we get better results if function pango_font_metrics_get_height()
is not used until version 1.50.6 and above of libpango. The difference is specially visible
with underscore characters in unscaled, standard DPI displays. This commit does that.
