Improve the number of images that are requested in the swapchain. For
mailbox presentation mode we select tripple buffering. For V-Sync
presentation mode we select double buffering.
In future we might want to make the presentation mode and swapchain
images dynamic based on the actual action that the user is performing.
When doing action that benefit from low latency (paint cursor) we should
select mailbox, otherwise we can use fifo to reduce CPU/GPU usage and
safe some energy usage along the way. See #136923 for design task.
