OptionsContainerWidget is a GUI widgets container that is meant to be
used for configuration dialogs tabs. It provides an interface subclasses
can implement for loading and saving settings from a configuration domain.
Prior to this change, a GUI layout was only affected by the screen size.
Now, a layout can additionally be influenced by the GUI dialog and widgets
that uses it. This capability is leveraged to implement the following
features:
* Layout elements that are not bound to a GUI widget do not take space.
This means that dialogs where the widgets shown depend on for example
a feature being enabled at configure time no longer have blank spaces.
* Widgets can define a minimal required size for their contents not to be
cut. For now this is only used for buttons so their width is always
sufficient for their caption not to be cut. This mechanism could be
applied to other widget types in the future.
DropdownButtonWidget is a button split in two parts vertically. Clicking
the left part triggers a default action. Clicking the right part shows a
list of other actions the user can choose from.
Using this widget on the launcher lets 'Mass add' be a secondary action
of the 'Add' button, removing the necessity of pressing the shift key to
access the feature.
Selecting whether a clipping variant of a draw call needs to be used is
no longer the responsibility to the caller. The clipping rect is now
part of the state of the renderer.
Also fix some of the draw calls to better apply the clipping rect.
Unfortunatedly the encoding used by ScummVM breaks the
speech-dispatcher, so after trying to say non-ascii character
the connection has to be restarted. So for now I am restricting
the GUI TTS to english only.
Out-of-bounds values are always indicative of a bug somewhere else,
but at least not crashing here allows the user to recover by
interacting with the slider control. The error will still be
obvious because the associated text field will display the
original weird value.
Changes theme stx files to specify TabWidget's type. That fixes wrong TabWidget height.
Changes TabWidget's getHeight() to return not only "children" height, but also tabs height. That fixes wrong clipping area.
Changes Widget's findWidget to use getHeight(). That fixes bug when widgets in the bottom of TabWidget were not reacting to the mouse events.
