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).

fix(D.2b): channel menu popup opaque + button label tracks selected target
- the popup inherited the chat window 0.75 opacity so the transcript bled through;
add UiRenderContext.PushAlphaAbsolute and draw the popup at absolute opacity.
- the "Chat" button was hardcoded; it now shows the active talk target (retail
updates it on selection). Exact textured menu-panel sprite is a follow-up (the
popup is a keystone UIElement_Menu construct, not in the chat LayoutDesc).

feat(D.2b): chat polish — typing fix, opacity, scrollbar 3-slice, retail channel menu
Visual-iteration batch (decomp-grounded), each fix verified against the retail screenshots:
- typing: UiElement.HitTest aborted on ClickThrough BEFORE walking children, so the
ClickThrough UiDatElement panels blocked hit-testing to the input/transcript inside
them. Check ClickThrough AFTER the child walk (it only gates whether THIS element
claims the hit). Restores input focus + typing.
- opacity: UiElement.Opacity + a UiRenderContext alpha stack applied to sprite/rect
draws (text bypasses it, stays sharp); chat frame Opacity=0.75 → translucent chat.
- brown sliver: grow the transcript panel up 9px to cover the dropped resize-bar strip.
- scrollbar: real 3-slice thumb (caps 0x06004C60/66 + tiled mid) + tiled track.
- max/min: shifted one button-width left of the scrollbar (dat right-anchors collide).
- system text now green (retail ChatMessageType 5; was yellow).
- word-wrap: transcript lines wrap to the panel width (greedy, ports GlyphList::Recalculate).
- channel menu reworked to retail gmMainChatUI::InitTalkFocusMenu: "Chat" button + a
TWO-COLUMN popup of the 14 talk-focus items (Squelch, Tell to Selected, Chat to All,
Tell to Fellows, ...) on a tan panel; channel items set the active outbound channel.
Build + 392 App tests green. Visual confirmation in progress.

DrawStringDat placed each glyph quad at the raw (often fractional) pen/origin.
When a bar resizes to a fractional width, the centered cur/max number lands on a
sub-pixel x and the glyph atlas (linear-filtered) smears — the 'unsharp at certain
sizes' artifact. Round each glyph's destination to whole pixels (the pen keeps its
true fractional advance, so spacing is unaffected) — matches retail blitting glyphs
to integer dest. User-confirmed sharp across resize widths.

The vitals cur/max overlay rendered with the consola TTF debug font,
which is wrong for the retail look. Port the retail dat-font render
path so the numbers use Font 0x40000000 (Latin-1, 16px, with outline
atlas) — the same font retail draws on the vitals window.
UiDatFont (new): loads the Font DBObj from the DatCollection and
uploads its two RenderSurface atlases (foreground glyph pixels
0x06005EE5 + background outline 0x06005EE6) through
TextureCache.GetOrUploadRenderSurface — the same direct-RenderSurface
path the D.2b chrome sprites use. Builds a char->FontCharDesc lookup
and exposes MeasureWidth + LineHeight. The per-glyph advance
(HorizontalOffsetBefore + Width + HorizontalOffsetAfter) is a pure
static so the pen math is unit-testable without GL or the dat.
UiRenderContext.DrawStringDat (new): two-pass per-glyph blit mirroring
SurfaceWindow::DrawCharacter (acclient 0x00442bd0) — the BACKGROUND
atlas sub-rect tinted black (outline) first, then the FOREGROUND
sub-rect tinted the text color (fill), with the pen accumulating the
retail advance the way the string loop does at 0x00467ed4. Respects
the UI transform stack. Skips the outline pass for fonts with no
background atlas.
No shader change was needed: the foreground atlas decodes A8 ->
(255,255,255,a), and ui_text.frag's RGBA-sprite path already
MULTIPLIES the texel by the per-vertex tint (texture(uTex,vUv)*vColor),
so tinting white+alpha by a color gives color+alpha (black outline,
text-color fill).
UiMeter: new DatFont property; the label renders via DrawStringDat
(centered with DatFont.MeasureWidth) when set, falling back to the
debug BitmapFont when null.
GameWindow: loads one UiDatFont for the vitals panel (under _datLock)
and assigns it to each UiMeter child; logs + falls back to the debug
font if the Font fails to load (never crashes).
Tests: 6 pure-logic UiDatFontTests for GlyphAdvance + MeasureWidth
(synthetic glyphs, negative bearings, missing chars, empty/null). Full
App UI suite green (84 passed).
DatReaderWriter member names verified via reflection on the 2.1.7
package: Font.{MaxCharHeight,BaselineOffset,ForegroundSurfaceDataId,
BackgroundSurfaceDataId,CharDescs} and FontCharDesc.{Unicode,OffsetX,
OffsetY,Width,Height,HorizontalOffsetBefore,HorizontalOffsetAfter,
VerticalOffsetBefore}.

Add uUseTexture==2 (RGBA modulate) branch to ui_text.frag so dat sprites
can be drawn through the existing 2D batcher without touching the font path.
TextRenderer gains _spriteBufs (per-GL-handle List<float>), DrawSprite(), and
a Flush block that issues one draw call per distinct texture with uUseTexture=2.
Also adds DepthMask(false) in the state-save block (restored to true after) to
prevent the transparent-quad pass from writing depth and corrupting the 3D scene
if the UI is flushed mid-frame.
TextureCache gains GetOrUpload(surfaceId, out width, out height) — caches pixel
dimensions alongside the GL handle so UI 9-slice geometry can compute slice UVs
from the source image size without a second decode.
UiRenderContext gains a DrawSprite forwarder that applies the current 2D
translate stack, matching the DrawRect / DrawRectOutline pattern.
