Text input fixes and enhancements (#4084) InputText, ScrollTextWidget, TextBoxWidget: - proper line scrolling when moving cursor or inserting/deleting text to behave like most text editors do - fix cursor navigation, optimize refreshes when moving only the cursor, don't recreate the textwidget when moving cursor up/down - optimize refresh areas, stick to "ui" to avoid a "partial" black flash every 6 appended or deleted chars InputText: - fix issue when toggling Show password multiple times - new option: InputText.cursor_at_end (default: true) - if no InputText.height provided, measure the text widget height that we would start with, and use a ScrollTextWidget with that fixed height, so widget does not overflow container if we extend the text and increase the number of lines - as we are using "ui" refreshes while text editing, allows refreshing the InputText with a diagonal swipe on it (actually, refresh the whole screen, which allows refreshing the keyboard too if needed) ScrollTextWidget: - properly align scrollbar with its TextBoxWidget TextBoxWidget: - some cleanup (added new properties to avoid many method calls), added proxy methods for upper widgets to get them - reordered/renamed/refactored the *CharPos* methods for easier reading (sorry for the diff that won't help reviewing, but that was needed) InputDialog: - new options: allow_newline = false, -- allow entering new lines cursor_at_end = true, -- starts with cursor at end of text, ready to append fullscreen = false, -- adjust to full screen minus keyboard condensed = false, -- true will prevent adding air and balance between elements add_scroll_buttons = false, -- add scroll Up/Down buttons to first row of buttons add_nav_bar = false, -- append a row of page navigation buttons - find the most adequate text height, when none provided or fullscreen, to not overflow screen (and not be stuck with Cancel/Save buttons hidden) - had to disable the use of a MovableContainer (many issues like becoming transparent when a PathChooser comes in front, Hold to paste from clipboard, moving the InputDialog under the keyboard and getting stuck...) GestureRange: fix possible crash (when event processed after widget destruction ?) LoginDialog: fix some ui stack increase and possible crash when switching focus many times.
