+On the musl C library, tests/timespec-text.c does not build, with the

+Indeed, struct timespec is defined in time.h, so we must include it.

+Multi-plane sub-sampled textures have partial width/height, e.g.
+YUV420/I420 has a full-size Y plane, followed by a half-width/height U
+plane, and a half-width/height V plane.
+
+zwp_linux_dmabuf_v1 allows clients to pass an explicit pitch for each
+plane, but for wl_shm this must be inferred. gl-renderer was correctly
+accounting for the width and height when subsampling, but the pitch was
+being taken as the pitch for the first plane.
+
+This does not match the requirements for GStreamer's waylandsink, in
+particular, as well as other clients. Fix the SHM upload path to
+correctly set the pitch for each plane, according to subsampling.
+
+Tested with:
+  $ gst-launch-1.0 videotestsrc ! waylandsink
