Robin Burchell	9b86eb9fad	WSCompositor: Allow a compose to bypass the timer when it first happens ... d66fa60fcf introduced the use of a timer to coalesce screen updates. This is OK, but it does introduce update latency. To help mitigate the impact of this, we now have a second (immediate) timer. When a compose pass is first triggered, the immediate timer will allow the compose to happen on the next spin of the event loop (so, only coalescing updates across a single event loop pass). Any updates that trigger while the delayed timer is running, though, will be delayed to that (~60fps) timer. This fixes #103.	2019-05-26 18:22:33 +02:00
Andreas Kling	7efd61fcf5	WindowSerer+LibGUI: Send multiple rects in invalidation/flush messages. ... This patch moves to sending up to 32 rects at a time when coordinating the painting between WindowServer and its clients. Rects are also merged into a minimal DisjointRectSet on the server side before painting. Interactive resize looks a lot better after this change, since we can usually do all the repainting needed in one go.	2019-04-20 17:23:35 +02:00
Andreas Kling	5eedb22834	Sprinkle use of AK::Vector in various places. ... Some of these are less helpful than others. Avoiding a bunch of mallocs in the event loop wakeup code is definitely nice.	2019-04-20 14:02:19 +02:00
Andreas Kling	98784ad3cb	WindowServer: Avoid overdraw by shattering dirty rects into unique shards. ... The algorithm I came up with is O(n^2) but given the small numbers of rects we're typically working with, it doesn't really matter. May need to revisit this in the future if we find ourselves with a huge number of rects.	2019-02-19 14:49:23 +01:00
