// This is an implementation of a mock Wayland compositor for testing
// It does not show anything on the screen, and is only as conforment as is required by GTK

// Useful regex for importing a Wayland protocol. First, copy from header file then:
// Find: (struct (\w+)_interface (\{?\n\t.*)*)[\{;]\n(\t[/ ]\*.*\n)+\tvoid \(\*(\w+)\)(\((.*(,\n)?)*\));\n\};((([^=]*\n)*)\nstatic const struct \w+ \w+ = \{\n((    \.\w+ = \w+\,\n)*)\};)?
// Replace with: \1;\n};\nstatic void \2_\5\6\n{\n    FATAL_NOT_IMPL;\n}\n\{10}\nstatic const struct \2_interface \2_impl = {\n    .\5 = \2_\5,\n\{12}};
// Then remove the struct artifact and replace this with a space: \n\t\s*
