Jan Arne Petersen 4653531e7a text: add pre-edit styling support to protocol
Also add a separate preedit-cursor event and add a commit argument to
preedit-string to allow to support commit on reset. Fix editor and
keyboard example to adapt to the protocol changes.

<interface name="text_model" version="1">
<description summary="text model">
A model for text input. Adds support for text input and input methods to
applications. A text_model object is created from a text_model_factory and
corresponds typically to a text entry in an application. Requests are used
to activate/deactivate the model and set information like surrounding and
selected text or the content type. The information about entered text is
sent to the model via the pre-edit and commit events. Using this interface
removes the need for applications to directly process hardware key events
and compose text out of them.
</description>
<request name="set_surrounding_text">
<description summary="sets the surrounding text">
Sets the plain surrounding text around the input position. Cursor is the
byte index within the surrounding text. Anchor is the byte index of the
selection anchor within the surrounding text. If there is no selected
text anchor is the same as cursor.

<request name="activate">
<description summary="request activation">
Requests the model to be activated (typically when the text entry gets
focus). The seat argument is a wl_seat which maintains the focus for
this activation. The surface argument is a wl_surface assigned to the
model and tracked for focus lost. The activated event is emitted on
successful activation.

wl_keyboard key_state. Modifiers are a mask for effective modifiers
