All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

| /* Copy a regular file from SRC_NAME to DST_NAME. | |
| If the source file contains holes, copies holes and blocks of zeros | |
| in the source file as holes in the destination file. | |
| (Holes are read as zeroes by the `read' system call.) | |
| When creating the destination, use DST_MODE & ~OMITTED_PERMISSIONS | |
| as the third argument in the call to open, adding | |
| OMITTED_PERMISSIONS after copying as needed. | |
| X provides many option settings. | |
| Return true if successful. | |
| *NEW_DST is as in copy_internal. |
