Add GtkTextHandle This is a helper object to allow text widgets to implement text selection on touch devices. It allows for both cursor placement and text selection, displaying draggable handles on/around the cursor and selection bound positions. Currently, this is private to GTK+, and only available to GtkEntry and GtkTextView.

Add GtkTextHandle This is a helper object to allow text widgets to implement text selection on touch devices. It allows for both cursor placement and text selection, displaying draggable handles on/around the cursor and selection bound positions. Currently, this is private to GTK+, and only available to GtkEntry and GtkTextView.

texthandle: Set a bigger input shape, covering the line height Now, even if the handles being rendered are small, the handle touch input shape will be as wide as the visible part of the rendered asset, and high enough to cover both the handle and the height of the line where the selection bound is. Also, make handles have the same virtual distance to the line top/bottom when a drag starts, so the handle doesn't jump to another line after a too short threshold.
