+Subject: [PATCH] add missing <cstdint> include
+
+Upcoming `gcc-13` made `<string>` leaner and does not include `<cstdint>`
+implicitly anymore. As a result build fails without the change as:
+
+    [  2%] Building CXX object CMakeFiles/wayland-scanner++.dir/scanner/scanner.cpp.o
+    scanner/scanner.cpp:378:3: error: 'uint32_t' does not name a type
+      378 |   uint32_t width = 0;
+          |   ^~~~~~~~
