This patch migrates all decoration rendering of i3 to cairo. Using the compile switch CAIRO_SUPPORT, rendering can be switched back to the previous XCB behavior, just like with the previous migration to cairo in i3bar. This patch also fixes a bug in draw_util.c where copying one surface to another would use incorrect coordinates if the source coordinates are not 0, 0. Furthermore, this patch implicitly fixes some minor issues in the decoration rendering which would be ignored previously due to the fact that errors would only show up in the event queue, but not cause the rendering code path to crash. One example is zero-height pixmaps which are not allowed. Using cairo, these would cause i3 to instantly segfault, so this patch avoids this. Lastly, this patch annotates other issues found but not fixed in this patch using TODO comments, e.g., the zero-height check not working correctly and the comment that it should probably work the same way for zero-width pixmaps. relates to #1278 |

Introduction ============ libi3 is an *INTERNAL* library which contains functions that i3 and related tools (i3-msg, i3-input, i3-nagbar, i3-config-wizard, i3bar) use. It is NOT to be used by other programs. Structure ========= Every function gets its own .c file, which in turn gets compiled into an .o object file. Afterwards, all .o files are archived into one static library (libi3.a). This library will be linked into all i3 binaries. The linker is able to eliminate unused .o files when linking, so only the functions which you actually use will be included in the corresponding binary.
