In order to apply the zoom transformation to the output matrix, Weston was doing the following: • Create a temporary matrix to hold the translation • Invert the translation matrix using weston_matrix_invert into another temporary matrix • Scale that matrix by the scale factor • Multiply the current matrix with the temporary matrix Using weston_matrix_invert to invert a translation matrix is over the top. Instead we can just negate the values we pass to weston_matrix_translate. Matrix multiplication is associative so creating a temporary matrix to hold the scale and translation transform should be equivalent to just applying them directly to the output matrix. |

Weston Weston is the reference implementation of a Wayland compositor, and a useful compositor in its own right. Weston has various backends that lets it run on Linux kernel modesetting and evdev input as well as under X11. Weston ships with a few example clients, from simple clients that demonstrate certain aspects of the protocol to more complete clients and a simplistic toolkit. There is also a quite capable terminal emulator (weston-terminal) and an toy/example desktop shell. Finally, weston also provides integration with the Xorg server and can pull X clients into the Wayland desktop and act as a X window manager. Refer to http://wayland.freedesktop.org/building.html for building weston and its dependencies. The test suite can be invoked via `make check`; see http://wayland.freedesktop.org/testing.html for additional details.
