MOUSE CURSOR TYPE AND VISIBILITY
================================
You can show and hide the mouse cursor with
void sapp_show_mouse(bool show)
And to get the current shown status:
bool sapp_mouse_shown(void)
NOTE that hiding the mouse cursor is different and independent from
the MOUSE/POINTER LOCK feature which will also hide the mouse pointer when
active (MOUSE LOCK is described below).
To change the mouse cursor to one of several predefined types, call
the function:
void sapp_set_mouse_cursor(sapp_mouse_cursor cursor)
Setting the default mouse cursor SAPP_MOUSECURSOR_DEFAULT will restore
the standard look.
To get the currently active mouse cursor type, call:
sapp_mouse_cursor sapp_get_mouse_cursor(void)
MOUSE LOCK (AKA POINTER LOCK, AKA MOUSE CAPTURE)
================================================

- sapp_desc needs a bool whether to initialize depth-stencil surface

- the UPDATE_CURSOR event currently behaves differently between Win32 and OSX
(Win32 sends the event each frame when the mouse moves and is inside the window
client area, OSX sends it only once when the mouse enters the client area)
- the Android implementation calls cleanup_cb() and destroys the egl context in onDestroy
at the latest but should do it earlier, in onStop, as an app is "killable" after onStop
