Description
Refreshes MipAdjustedRenderTarget / MipAdjustedBrush for the current mip level. Returns true if the brush is drawable this frame. False is "skip this frame" - it covers transient cases like the mip material's shaders still compiling, where bInvalidatedMipTexture stays true so the next paint retries. Callers should fall back to plain Brush, not treat false as fatal.
