+==========
+
+
+Description
+-----------
+Support w3m images hack. Similar to the patch at the FAQ, but it's simpler,
+smaller, and doesn't disable double-buffering in st.
+
+Same as the FAQ patch, the cursor line is deleted at the image, because st
+always renders full lines, even when most of it is empty.

+Subject: [PATCH] support w3m images
+
+w3m images are a hack which renders on top of the terminal's drawable,
+which didn't work in st because when using double buffering, the front
+buffer (on which w3m draws its images) is ignored, and st draws only
+on the back buffer, which is then copied to the front buffer.
+
+There's a patch to make it work at the FAQ already, but that patch
+canceles double-buffering, which can have negative side effects on
+some cases such as flickering.
+
+This patch achieves the same goal but instead of canceling the double
+buffer it first copies the front buffer to the back buffer.
+
+This has the same issues as the FAQ patch in that the cursor line is
+deleted at the image (because st renders always full lines), but
+otherwise it's simpler and does keeps double buffering.
