This patch changes the interface of Nitpicker to support dynamically dimensioned virtual frame buffers. This solves two problems: First, it enables a client to create a connection to nitpicker without donating much session quota in advance. The old interface required each screen-size-dependent client to donate as much memory as needed to allocate a screen-sized virtual framebuffer. For clients that are interested int the screen size but cover just a small portion of the screen (e.g., a banner, a menu, an applet that sits in the screen corner), this overprovisioning is painful. The new interface allows such clients to upgrade the session quota for an existing session as needed. Second, because each nitpicker session used to have a virtual frame buffer with a fixed size over the lifetime of the session, a client that wanted to implement a variable-sized window had to either vastly overprovide resources (by opening a session as large as the screen just in order to be prepared for the worst case of a maximized window), or it had to replace the session by a new one (thereby discarding the stacking order of the old views) each time the window changes its dimensions. The new interface accommodates such clients much better. |
