Andreas Kling	0b0514d46b	LibGUI+WindowServer: Use anonymous files for window backing stores :^) ... This patch replaces the use of shbufs for GUI::Window backing stores with the new anonymous files mechanism. Backing bitmaps are now built on memory allocated with anon_create(). They are passed across the IPC socket as IPC::File. This means that WindowServer now pledges "recvfd" and graphical clients need to pledge "sendfd" to work. To support the cached bitmap swapping optimization on the WindowServer side, each backing store is assigned an incrementing serial number on the client side. (This allows us to re-use an already mapped file.)	2021-01-15 13:57:00 +01:00
Andreas Kling	96f8fcdcba	LibGUI: Add a WindowBackingStore class ... Instead of storing the back/front buffers of a GUI::Window as just Gfx::Bitmap, wrap them in a WindowBackingStore class. This will allow us to add more information alongside the bitmaps while keeping the back/front swapping logic simple.	2021-01-15 10:54:19 +01:00
