Parseh a0.4.0

Added

• LaTeX drawings: a ::::latex block, or [...]{latex} inline, compiled by LaTeX itself, beside the formulas MathJax draws
• The same drawing on screen, in the PDF, in an HTML export and on a phone; a live preview kept only once it is saved
• A drawing that cannot be made shows its source and one line saying why, with the button that mends it
• The sheet that draws a block: its preview filling its pane beside the source, a caption, size and position folded away
• Settings → LaTeX drawings, styled like the rest of Settings: named themes of packages, languages, a font, a preamble and a compiler
• Themes exported and imported as files; a rename rewrites every block that names the theme
• A theme's packages beyond the base kept in Parseh's own folder, listed with the base, asked about and gotten one at a time
• More packages to pick from: syntax trees and dependency arcs, the IPA, pinyin over Chinese characters
• A deck's exercises filtered by where they came from, beside its text and tag filters
• Flashcards that are asked both ways: both (random) and both (repeat), the second two linked cards in a deck
• The transliteration cloud works on an exported page and on the guide's own words
• On a phone's video, the subtitles have a text size of their own, reached in full-screen too

Changed

• Every Settings page starts with the bar of its doors, Network included
• Deleting a document asks in the studio's own window, and the card leaves the list at once
• Documents, decks, bundles and shelves are stored in a new shape: going back to a0.3.3 says so first
• The size sliders of books and videos reach further, at both ends

Fixed

• Exporting a page to HTML from another device could land on "Parseh cannot be reached": it shows a bar now
