However, with X11R4, the folks at MIT incorporated a “shapes” extension, so windows need not be rectangular. The upper-left corner of an X window is considered to be its origin (see Figure 2-3). The xaxis increases as you go left while the y-axis increases as you go down. All coordinates in X are relative, that is, from the window’s point of view all things start at 0,0. If a window is created and is offset from the root window at 100,100 the root window’s perspective of the child’s origin is 100,100 while the child views it as 0,0.
The “palette” is a colormap. Think of a colormap as an array of colors (kind of like a look-up table). Some interesting things happen with colormaps and window managers. Clients can install their own colormaps that may be different than other clients’, so when the client has the focus, the window manager installs the colormap. But, since it differs from the one being used by other clients, and the colormap indices do not change when new colormaps are installed, the other clients might not appear in their true colors.
