Subject: [PATCH 216/293] spice: split qemu_spice_create_update
|
|
|
93b7e3 |
|
|
|
93b7e3 |
Creating one function which creates a single update for a given
|
|
|
93b7e3 |
rectangle. And one (for now) pretty simple wrapper around it to
|
|
|
93b7e3 |
queue up screen updates for the dirty region.
|
|
|
93b7e3 |
|
|
|
93b7e3 |
[ v2: also update bounding box ]
