It follows the C++ source function by function, so upstream documentation, examples and the demo apply almost directly.

 Every snippet in this README is run by [`tools/test/scripts/t_readme.luau`](/tools/test/scripts/t_readme.luau), and every image was rendered by this port with [`tools/screenshots/make.py`](/tools/screenshots/make.py).
 ### How it works (Roblox backend)
 Dear ImGui itself never draws anything: every frame it produces `ImDrawData`, a list of textured, coloured triangles plus clip rectangles, and expects the backend to put them on screen. On desktop that is a few GPU draw calls. Roblox has no API to draw arbitrary triangles in 2D, so the Roblox backend ([backends/imgui_impl_roblox.lua](/backends/imgui_impl_roblox.lua)) does what a GPU would do, in Luau, and pushes the result into **EditableImages**.
 **Why software rasterization?** The alternatives don't fit Dear ImGui:
 - *One GUI Instance per widget/shape* (what most Roblox UI libraries do) means re-creating, re-parenting or diffing thousands of Instances every frame, can't express anti-aliased curves, per-vertex gradients or font-atlas glyphs, and would no longer be Dear ImGui's renderer output.
 - *Rasterizing the draw data* keeps the output identical to Dear ImGui's: the same fonts, anti-aliasing, rounding and gradients, and every widget (including custom `ImDrawList` drawing) works without backend support.
 The cost is CPU time in Luau, so the backend is built around **not drawing**:
 1. **Layers per window.** Every draw list (one per top-level window, popup, tooltip) gets its own `Frame` with `ZIndex` following Dear ImGui's draw order. Its content is rasterized relative to the window, so **moving a window only changes the Frame's `Position`**; no pixel is redrawn or uploaded.
 2. **Tiles.** Each layer is covered by 128×128 EditableImage tiles (`ImageLabel`s). Every primitive is hashed (positions relative to the layer, UVs, colours, texture, clip) into the tiles it touches. **Only tiles whose hash changed are re-rasterized and uploaded**, and only the dirty region of those (`WritePixelsBuffer` with a sub-rectangle). A static UI uploads nothing.
 3. **Scrolling reuses pixels.** Window content is a separate layer inside a `ClipsDescendants` frame sized to the window's visible area, positioned at the scroll offset. Scrolling moves it like dragging moves a window; only rows entering view are drawn. Decorations (title bar, borders, scrollbar) stay in their own layers.
 4. **Skipping unchanged windows.** Vertices are stored in a flat Luau `buffer` (36 bytes each) instead of tables. Before any per-tile work, a window's raw vertex/index bytes are compared with last frame's; if identical, its layers are just restacked.
 5. **Fast rasterizer.** `@native` functions; axis-aligned quads (most rects and every glyph) take a span-fill path, flat rows are copied instead of re-blended, gradient rects (color pickers) are filled per row, and only real triangles (anti-aliased edges, curves) use the generic edge-function rasterizer.
 6. **Render rate.** Tiles update at most `SetRenderRate(hz)` times per second (default 60), optionally lower while scrolling/resizing (`SetBusyRenderRate`). Your UI code and Dear ImGui's logic still run every frame, so input is never dropped.
 **Input.** Mouse and keys come from `UserInputService`. While the mouse is over Dear ImGui (`io.WantCaptureMouse`), the tiles are `Active`, so clicks and the wheel don't reach the game (camera zoom). Games can't read the clipboard, so while a text field is active a hidden `TextBox` holds focus: the OS delivers typing (any layout), paste and copy/cut through it, and its text mirrors Dear ImGui's current selection. Fonts are TTFs rasterized by the ported stb_truetype into the font atlas, which becomes a backend texture like any image (`CreateTexture` works for your own pixels too).
 **Instances inside windows.** The backend can place your own Instances (e.g. a `ViewportFrame`) inside a window's layer, so they stack, clip and move with it; see the `ImGui.Embed` widget in [examples/example_roblox/main.client.luau](/examples/example_roblox/main.client.luau).
 ### Demo
 Calling `ImGui.ShowDemoWindow()` creates a demo window that showcases a variety of features and examples. The code is in [imgui_demo.lua](/imgui_demo.lua), like upstream's `imgui_demo.cpp`. **It's strongly recommended to keep it at hand as a reference**: you can find the code for any widget you see by searching for its label.

 Most of the remaining cost is widget logic (your UI code and Dear ImGui's per-widget work), which runs every frame by design. Use `ImGuiListClipper` for long lists.
 Windows that rarely change can opt in to caching: `ImGui.SetNextWindowCached(key)` keeps last frame's drawing and makes `Begin` return `visible = false`, so your code for that window doesn't run. It refreshes when `key` changes, while the window is hovered, focused or active (plus one frame after), and when it appears, moves, resizes, scrolls, collapses or is docked. An idle 200-widget window goes from ~2.2 ms to ~0.15 ms per frame.
 ```lua
 local stats = { version = 0, kills = 0 }
 local function StatsWindow()
    ImGui.SetNextWindowCached(stats.version) -- bump stats.version whenever stats change

 Most of the remaining cost is widget logic (your UI code and Dear ImGui's per-widget work), which runs every frame by design. Use `ImGuiListClipper` for long lists.
 Windows that rarely change can opt in to caching: `ImGui.SetNextWindowCached(key)` keeps last frame's drawing and makes `Begin` return `visible = false`, so your code for that window doesn't run. It refreshes when `key` changes, while the window is hovered, focused or active (plus one frame after), and when it appears, moves, resizes, scrolls, collapses or is docked. An idle 200-widget window goes from ~2.2 ms to ~0.15 ms per frame.
 ```lua
 local stats = { version = 0, kills = 0 }
 local function StatsWindow()
    ImGui.SetNextWindowCached(stats.version) -- bump stats.version whenever stats change
    local _, visible = ImGui.Begin("Stats")
    if visible then -- false while the cached contents are reused
        ImGui.Text("Kills: %d", stats.kills)
    end
    ImGui.End()
 end
 ```

 -- Custom widget: ImGui.Embed(id, size, flags, init) -> Frame
 -- Reserves a widget-sized area in the current window and shows a real Frame there, so any Instances (UI, a
 -- ViewportFrame, ...) can live inside an imgui window. Immediate-mode friendly:
 --   * one Frame per id (per window, through the ID stack, like any widget); `init(frame)` runs only when it is created
 --   * call it every frame the Frame should be visible; when it isn't called (window closed/collapsed, tab or tree node
 --     closed, scrolled fully out of view) the Frame is hidden, never destroyed, so your Instances keep their state
 --   * size uses imgui sizing (ImVec2(-1, h) = fill width, 0 = default), style gives padding/rounding/background/border
 --   * returns the Frame: edit properties, add or remove children any time
 -- ImGui.DestroyEmbed(id) removes it for good (call while the same window is current, like the widget itself).
