calculateScaledDpCompose

EN Shared pure-math scaling kernel used by toDynamicScaledDp and toDynamicScaledPx.

Algorithm summary:

1. Applies Inverter rules to swap the effective DpQualifier based on orientation.

2. If ignoreMultiWindows is true, detects split-screen via layout flags; if active, returns baseValue unchanged so the UI does not over-scale in a small window.

3. For the common path (SMALL_WIDTH + DEFAULT inverter + no custom sensitivity), delegates to DimenCache.calculateRawScaling which reads the pre-computed factors from DimenCache.ScreenFactors — one float multiply, zero extra allocations.

4. For other qualifiers or custom sensitivity, reads the screen dimension from Configuration and performs the scaling formula inline.

Performance: Simple paths without Aspect Ratio complete in ~2 ns (single multiply). Paths with Aspect Ratio require ~41 ns on Snapdragon 888 (includes ln() fallback). Results are memoized by the surrounding remember block and DimenCache.

PT Núcleo de escalonamento puro compartilhado por toDynamicScaledDp e toDynamicScaledPx.

Resumo do algoritmo:

1. Aplica as regras de Inverter para trocar o DpQualifier efetivo conforme a orientação.

2. Se ignoreMultiWindows for true, detecta split-screen via flags de layout; se ativo, retorna baseValue sem escalar.

3. Para o caminho comum (SMALL_WIDTH + DEFAULT + sem sensibilidade customizada), delega para DimenCache.calculateRawScaling com os fatores pré-calculados.

4. Para outros qualificadores ou sensibilidade customizada, lê a dimensão da tela do Configuration e executa a fórmula de escalonamento inline.
