- SPECTRUM_PIXELS 1024→4096 + настройка display_pixels (лимит точек
анализатора, SetDisplayResLimit); web-зеркало остаётся 1024 —
max-децимация в SnapshotPixels
- палитры водопада Classic/Inferno/Turbo + регулятор gamma (в LUT),
настройки wf_palette/wf_gamma, страница Waterfall → группа Rendering
- GL-водопад переведён на общий LUT/AGC-уровни базового класса
(убраны дубли ColorForDB/UpdateLevels)
- явные glViewport в GL-вьюхах умножаются на PixelScale (HiDPI),
текстура водопада — в физической ширине

WaterfallView: drop per-frame TLazIntfImage + LoadFromIntfImage (device
bitmap recreation + full pixel-format conversion every frame). Write
pixels directly into the bitmap via BeginUpdate/ScanLine like
SpectrumView already does, with platform-native byte order (ARGB on
Cocoa, BGRA elsewhere).
Replace per-pixel float colorization with a 512-entry dB->color LUT
rebuilt only when WfLow/WfHigh/theme change beyond a small threshold.
Turn the bitmap itself into a ring buffer: each frame builds a single
new row and writes one ScanLine; scrolling is done at paint time via two
CopyRect calls. Removes both full-frame passes per frame (image memmove
+ buffer->bitmap copy), cutting per-frame cost from O(W*H) to O(W). TX
mode preserved by leaving out-of-span columns untouched in the row buf.
SpectrumView: rewrite the per-frame alpha-restore pass from a strided
per-byte loop to a sequential per-dword OR with the alpha mask
(bit-identical output, sequential memory access).

TSpectrumView remains the public facade for MainForm; waterfall, S-meter,
and ruler rendering are now in isolated units. Dead code removed.
