Code-review follow-ups to the ImGui inspector:
- Add public UiRoot.Pick(x,y) over the private HitTestTopDown (honors
Z-order + modal exclusivity); StudioWindow uses it instead of a manual
UiElement.HitTest with subtracted ScreenPosition.
- RenderStack : IDisposable — disposes the GL pieces it owns in one place;
StudioWindow OnClosing + Dispose both call _stack?.Dispose(), closing the
error-path leak (only UiHost was disposed on the Dispose-without-OnClosing
path).
- Drop the stale _dt field; OnRender passes its own dt to Tick + BeginFrame.
- Fix a stale PanelFbo comment.

Visual gate 2 (user): the "Slots" toggle caption was visible but unclickable.
Root cause (UiRoot.OnMouseDown/OnMouseUp): a left-press on a non-drag-source
widget inside a whole-window-Draggable frame (the inventory window's IA-12
drag) set _windowDragTarget; OnMouseUp then early-returned before emitting the
Click. So the paperdoll Slots button (the first plain button inside the
draggable inventory frame) never received its click. Chat/toolbar buttons
escape this — their frames aren't whole-window-draggable.
Fix (toolkit, root cause not band-aid): add UiElement.HandlesClick (a virtual
opt-out parallel to IsDragSource); UiButton overrides it true; OnMouseDown
routes a HandlesClick press to the widget (like CapturesPointerDrag) instead of
the window-drag, so OnMouseUp emits the Click. 2 regression tests lock it
(HandlesClick widget in a Draggable frame emits Click; a plain one doesn't).
Build + full App suite green (596, +2).

BringToFront sets a window's ZOrder one past the max among its peers.
ShowWindow now raises on open; OnMouseDown raises any pressed top-level
window (retail-faithful stacking). Existing drag/resize tests unaffected
(raise only touches ZOrder, not geometry).

A Dictionary<string,UiElement> registry on UiRoot with RegisterWindow +
Show/Hide/Toggle. Show/Hide flip UiElement.Visible (already gates
Draw/Tick/HitTest); Toggle returns the new visibility; unknown names are
no-ops. WindowNames.Inventory const shared by mount/registry/toggle.

UiElement.MaxHeight + ResizableEdges mask; UiCollapsibleFrame snaps height to the nearer
of {collapsed,expanded} and toggles row-2 visibility; GameWindow computes the two heights
from the layout + top-anchors the content. Amends IA-17. UiNineSlicePanel unsealed to
allow subclassing.

Found at visual verification: an occupied UiItemSlot sits inside the Draggable
toolbar frame (UiNineSlicePanel.Draggable=true), so UiRoot.OnMouseDown's FindWindow
returned the frame and the window-move branch won — press+drag on a slot moved the
whole bar instead of picking up the item. The slot wasn't CapturesPointerDrag (that
path is for self-driven text-selection and suppresses the BeginDrag promotion), and
UiRoot had no path for "a drag-source inside a draggable window."
Fix: add UiElement.IsDragSource (virtual, default false); UiItemSlot overrides it to
`ItemId != 0` (occupancy-gated). UiRoot.OnMouseDown now prioritizes IsDragSource over
window-move — an OCCUPIED slot starts the item drag (promotes to BeginDrag on >3px),
an EMPTY slot falls through to the IA-12 whole-window-drag so the bar stays movable
by its empty cells / chrome. UiRoot stays item-agnostic (reads only the bool). This
REDUCES divergence (occupied cells now drag like retail) within IA-12's umbrella — no
new register row.
Regression tests reproduce the LIVE topology (slot inside a Draggable frame); the
earlier RootWithBoundSlot tests put the slot directly under the root, so they could
not catch it. Full suite 493 pass / 0 fail / 2 skip.

The retail-look render + focus primitives this chat pass builds on:
- TextRenderer: an OVERLAY layer (sprite/rect/text buckets flushed AFTER the
normal layer) so an open popup composites on top of everything incl. rect
panel backgrounds; a DrawFill primitive (solid quad via a 1x1 white texture)
routed through the SPRITE bucket so a panel background draws UNDER its text
instead of being washed by the later rect bucket; and the text pass now
disables SampleAlphaToCoverage + Multisample so glyph alpha edges aren't
dithered into MSAA coverage (the "fuzzy text") — self-contained GL state
per feedback_render_self_contained_gl_state.
- UiRenderContext.DrawStringDat: snap the line baseline to a whole pixel ONCE
then add the integer per-glyph offset (retail DrawCharacter takes an int
pen-Y + schar m_VerticalOffsetBefore) — fixes the "letters dip down" jitter
at a fractional line origin. Outline pass is now opt-in (retail gates it per
element via SetOutline; default off = crisp fill-only). Adds DrawFill +
Begin/EndOverlayLayer.
- UiElement: OnDrawOverlay + DrawOverlays (second traversal), FindRoot (blur
self), ResetAnchorCapture (re-baseline an anchored element after reflow).
- UiRoot: runs the overlay pass after the main tree; Tab/Enter focuses the
DefaultTextInput (write-mode activation); a left click on a non-edit target
blurs the focused input (exit write mode without submitting).

Windows-like selection in the retail chat window: left-click-drag selects
characters, Ctrl-C copies, Ctrl-A selects all. The selected span paints a
translucent highlight behind the text.
- UiElement.CapturesPointerDrag: a per-element opt-out so an interior drag is
delivered to the widget (text selection) instead of moving/resizing the host
window. UiRoot.OnMouseDown honours it AFTER edge-resize (a resizable window
is still resizable from its frame) and BEFORE window-move.
- UiChatView: AcceptsFocus + IsEditControl + CapturesPointerDrag; caches the
OnDraw layout so OnEvent hit-tests the same geometry; HitChar maps a local
point to (line,col) with glyph-midpoint caret snapping; SelectedText joins a
multi-line span with \n; Ctrl-C writes to IKeyboard.ClipboardText (only when
non-empty, so an empty copy never clobbers the clipboard).
- UiHost exposes the wired IKeyboard (clipboard + Ctrl modifier state).
Adversarial-review fix (the 99 tests would have stayed green without it): a
coordinate-frame mismatch between MouseDown and MouseMove. UiRoot.OnMouseDown
dispatched HitTestTopDown's coords, which are relative to the TOP-LEVEL child,
while MouseMove/MouseUp use target.ScreenPosition. For the chat view inset at
(8,8) inside its window the anchor landed ~8px off the click. OnMouseDown now
delivers target-LOCAL coords like the other mouse events. Added a UiRoot
regression test asserting MouseDown and MouseMove share the target-local frame
for a nested child.
Decomp ref: SurfaceWindow text/selection model; clipboard via Silk.NET
IKeyboard.ClipboardText. Built with the chat-select-copy implement->review
workflow.

Add ResizeX/ResizeY bool properties to UiElement (both true by default).
HitEdges() in UiRoot masks out locked axes after edge detection, so a
locked edge falls through to window-move behaviour — matching retail,
where the vitals bar height is fixed and only widens.
MarkupDocument.Build() parses an optional resize="x|y|both|none"
attribute on <panel>; vitals.xml gets resize="x" to enforce the
horizontal-only constraint in all instances of the panel.
Two new tests: HitEdges_RespectsResizeAxisLock (UiRootInputTests) and
Build_ResizeAttrX_SetsHorizontalOnly (MarkupDocumentTests). 11/11 green.

Add parallel resize mode to the UiRoot retained-mode input state machine.
A left-drag starting within ResizeGrip=5px of a Resizable window's edge or
corner resizes it (min-size clamped); interior drags on a Draggable window
still reposition it.
Changes:
- UiElement: Resizable, MinWidth, MinHeight properties
- UiRoot: ResizeEdges flags enum; _resizeTarget state fields; FindWindow
(replaces FindDraggable, matches Draggable||Resizable); HitEdges (static,
internal, testable); ResizeRect (static, public, testable); OnMouseDown
checks edge-grip before move; OnMouseMove resize branch precedes move;
OnMouseUp clears _resizeTarget
- UiNineSlicePanel: Resizable = true (retail windows are resizable)
- UiRootInputTests: 4 new tests — ResizeRect_RightBottom, ResizeRect_LeftTop
(min-clamp + origin shift), HitEdges_DetectsCornerAndInteriorNone,
EdgeDrag_ResizesPanel_InteriorDragMoves (full integration path)
Note on test coordinate: right-edge grab uses x=298 (2px inside the panel's
hit-test boundary) rather than x=300 (exactly at edge, misses OnHitTest's
strict `<` check). This is intentional — the grip zone extends inward from
the edge boundary, so a click 2px inside correctly lands in both the
hit-test rect AND the resize-grip zone.

- UiElement: add Draggable flag; left-drag on a draggable element repositions
it as a floating window instead of starting a drag-drop sequence.
- UiRoot: add WantsMouse/WantsKeyboard properties (mirrors ImGui's WantCaptureMouse
pattern); add FindDraggable helper; inject _windowDragTarget state machine into
OnMouseDown/OnMouseMove/OnMouseUp so draggable windows track the pointer offset.
- UiNineSlicePanel: set Draggable=true so retail window frames are movable by default.
- GameWindow: OR _uiHost?.Root.WantsMouse|WantsKeyboard into the SilkMouseSource
wantCaptureMouse/wantCaptureKeyboard delegates and the direct MouseMove gate so
game actions (movement, world-pick) are suppressed while the pointer is over a
retail window — no double-handling with the InputDispatcher.
- GameWindow: wire all Silk Mice/Keyboards to UiHost after construction so the
UiRoot tree receives live input.
- Tests: 3 new UiRootInputTests covering WantsMouse hit-test, window-drag
reposition, and non-draggable panel immobility.
