The canvas gave the map no mouse surface of its own, on the reasoning that 1.12's
`WorldMapButton` covers the same rect and sits above it. The button is pinned INSIDE the canvas
child, so it scales with it: measured at the world view with OpenMapClassic driving, at grom's
own 2560x1440, a 23x16 px button inside a 701x468 px window. Every press on the other 99%
reached the next frame that takes the mouse — `WorldMapFrame`, which pfUI makes a
`RegisterForDrag("LeftButton")` handle for the whole window. So dragging the map moved the
window, and a click never reached `ProcessCanvasClickHandlers`, which is the only way a map pin
is ever dropped.
The container takes the mouse and the wheel now and drives the same controller. The frame level
mattered as much: the hit sweep probes one `(strata, level)` plane in link order and a parent is
linked before its children (`0x764aa0`), so a container tied with `WorldMapFrame` still lost
every press to its own parent. It is re-seated to `map:GetFrameLevel() + 1` on every show,
because the window is level 0 while the canvas builds and level 1 once `ShowUIPanel` has raised
it.
With the click arriving, a pin still stored nothing: `Map/Pins.lua:57` trims the note with
`strtrim`, which was deliberately absent. `script/stdlib.rs` still refuses it on the 1.12
surface, for the reason written there; this build claims ClassicAPI, whose client does have it,
so it lands in `compat/classic_api/string_trim.rs` with both spellings. Eight bare call sites in
the corpus, one of them in pfUI's search box on every keystroke.
`SCALE_RATE` 10 -> 24. A 0.7 s half-life was tolerable only while a wheel notch could not
accumulate; now that they add up the glide is what you feel ("scrolls past where I stop
scrolling").
`BenillaMapTextures(uiMapID)` is `GetExploredMapTextures` without the explored filter. Reveal
mode draws unexplored overlays out of a retail FileDataID table this client resolves none of —
captured with the fog default and with reveal, the same view came back pixel-identical, 0 by
`compare -metric AE`. The overlays were never missing, only their names: `Map/RevealFromClient.lua`
in `Addon_Ports/openmap_port` rebuilds the table from this, with paths.
Also in the port, not here: the arrow is placed through OpenMap's own coordinates, because
1.12 measures `GetPlayerMapPosition` against Blizzard's world and continent art and the stitched
map is a different projection.
