VOMD v1.2.0

Added

• Select and copy text. Drag to select (a drag that starts on a link selects, and a click still follows it), double-click for a word, triple-click for a paragraph, heading, code block or table row, Shift+click to extend, Ctrl+A for everything, and drag past the top or bottom of the window to scroll. Ctrl+C (also Ctrl+Insert, Ctrl+Shift+C and the Copy key) copies plain text: list items start with - , quoted lines with > , table cells are tab-separated, an image is its alt text and a link its text. The text is made only when a program pastes it, so copying a whole 5 MB document costs no memory until then (X11 INCR and Wayland pipes, in pieces of 64 KiB). On X11 and Wayland a selection made with the mouse (and Ctrl+A) is also the primary selection, pasted with a middle click; the new primary_selection = on|off setting turns that off. As the window closes on X11 the clipboard manager, if there is one, is asked to keep the clipboard. Needs the new clipboard feature, on by default; the smallest build leaves it out.
• Esc clears the selection before it quits (after closing the toolbar's menu, as before).
• A copy button on code blocks, as on GitHub: while the pointer is over a fenced or indented code block, a button shows in its upper right corner, and a click copies the block's code to the clipboard (not the primary selection, and a selection is left alone). The code is as written, with its tabs, indentation and blank lines, without the language tag, without the quote marks or list indent of what holds the block, and without a line break after the last line; a block of several MB is made only when something pastes it. The button turns into a check mark for two seconds, lights up and shows the hand under the pointer, scales with the zoom and the display, and is left off blocks too small for it. If there is no clipboard, a note says so. Part of the clipboard feature, so the smallest build has none.

Fixed

• An image decode that started just as the images wanted changed is counted in the room the image cache keeps free. Before, the cache could briefly fill the memory that decode used.
• With remote images on, a picture near the window could be fetched again and again after a few arrived at once: each body let in was the first thing the next one's room was made from.

Budgets, measured on the release runner

A shared runner is two to three times slower than the machine the time budgets
are for, so start and scroll times are reported here, not gated.
