executed. This allows clients to throttle themselves against the
server and implement smooth animations.
ISSUES:
Include panel and desktop background in wayland?
How does clients move their surfaces? set a full tri-mesh every time?
How does the server apply transformations to a surface behind the
clients back? (wobbly, minimize, zoom) Maybe wobble is client side?
How do apps share the glyph cache?
Input handling - keyboard focus, multiple input devices, multiple
pointers, multi touch.
Drawing cursors, moving them, cursor themes, attaching surfaces to
cursors. How do you change cursors when you mouse over a text
field if you don't have subwindows?
synaptics, 3-button emulation, xkb, scim
changing screen resolution, adding monitors.
What to do when protocol out buffer fills up? Just block on write
would work I guess. Clients are supposed to throttle using the bread
crumb events, so we shouldn't get into this situation.
When a surface is the size of the screen and on top, we can set the
scanout buffer to that surface directly. Like compiz unredirect
top-level window feature. Except it won't have any protocol state
side-effects and the client that owns the surface won't know. We lose
control of updates. Should work well for X server root window under
wayland.
Throttling/scheduling - there is currently no mechanism for scheduling
clients to prevent greedy clients from spamming the server and
starving other clients. On the other hand, now that recompositing is
