GLX backend: Avoid rebinding pixmap on window damage. Probably could improve performance on rapid window content changes, but is known to break things on some drivers (LLVMpipe). Recommended if it works.

GLX backend: GLX buffer swap method we assume. Could be `undefined` (0), `copy` (1), `exchange` (2), 3-6, or `buffer-age` (-1). `undefined` is the slowest and the safest, and the default value. `copy` is fastest, but may fail on some drivers, 2-6 are gradually slower but safer (6 is still faster than 0). Usually, double buffer means 2, triple buffer means 3. `buffer-age` means auto-detect using 'GLX_EXT_buffer_age', supported by some drivers. Useless with *--glx-use-copysubbuffermesa*. Partially breaks `--resize-damage`. Defaults to `undefined`.
