First step of split backend into modules This commit introduced a new, modular backend interface. The interface is not very good, since I don't think I fully understand all the requirements writing a backend have. But this is a good first step. This commit also includes an initial xrender backend written using the new interface, and some opengl backend related helper functions, which are taken from the old opengl backend. However, there is not integration with the core compton yet. compton will still use the old backend code. This commit is here so we can get the automated build test. What is implemented in the new xrender backend: * Windows with transparency * Shadow * Opacity * Wallpaper (getting the root pixmap) * Blur Known problem with the xrender backend: * It is slower Things that still need to be figured out: * What is the better way to add vsync to the new backends Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com> 2018-10-04 05:46:18 +08:00			`# enable xrender`
Let old/new backends co-exist Now both the old and the new backends are compiled in, the user can choose which one to use with a command line switch. Lower the barrier for testing.

Reuse some code from the new gl backend Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com> 2019-01-28 02:16:28 +08:00
Refactor FBConfig lookup Background: To bind a Xorg window content to a OpenGL FBConfig, which has to match the color format the Xorg window is using. Previously, compton just find a FBConfig that has the same depth. This led to chjj/compton#477, which has been fixed by a ugly hack. The commit refactor the lookup mechanism to take as much into consideration as we reasonably can. Hopefully preventing similar breakages in the future. Also, some code sharing between the old and new glx backend. Signed-off-by: Yuxuan Shui <yshuiv7@gmail.com> 2019-02-04 00:41:04 +08:00			`# enable opengl`
