Inheritance diagram for ConsoleForge.Layout.SubRenderContext:

Public Member Functions
void	RegisterWidget (IWidget widget, Region region)
	Record that widget was rendered at region .Used by the render cache for next-frame reuse. Default implementation is a no-op.
void	SetCursorDescriptor (CursorDescriptor cursor)
	Set cursor on the Rendering Context.
	SubRenderContext (IRenderContext parent, Region region)
	Initialises a sub-context that forwards writes to parent but restricts rendering to region .
bool	TryReuseWidget (IWidget widget, Region region)
	If widget (same reference) was rendered at the same region last frame, copy its cells from the previous buffer and return true.Caller should skip rendering that widget. A hit re-registers the widget for the current frame, so the caller must not call RegisterWidget again for it. Default implementation returns false (no caching).
void	Write (int col, int row, string text, Style style)
	Write a styled string at an absolute terminal position.The call is a no-op if (col, row) falls outside Region.
void	WriteRawEscape (Region region, IRawEscapePayload payload)
	Register a raw escape payload for region .All terminal cells covered by the region are sentinel-filled so the cell diff does not overwrite the image with styled spaces. The payload's sequences are emitted after the full cell-diff pass in the same frame, preceded by a cursor-move to region 's top-left corner. Re-emission is skipped when IRawEscapePayload.ContentHash and the region both match the previous frame (hash-based deduplication). Default implementation is a no-op — test fakes and SubRenderContext override this.

Properties
ColorProfile	ColorProfile [get]
	Detected terminal color capability.
CursorDescriptor?	Cursor [get]
	Cursor information for TextArea and TextInput widgets.
ResolvedLayout	Layout [get]
	Resolved layout for the current frame.Container widgets use this to retrieve child regions without re-running layout.
Region	Region [get]
	The allocated region this sub-context is restricted to.
Theme	Theme [get]
	Active theme for style inheritance.

Detailed Description
