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.
