showcase: stretch SVG to fill browser window in both axes (non-uniform scale)
Replace the uniform min(W/CHART_W, H/CHART_H) scale — which left blank bars
along the shorter axis — with independent x/y scales:
sx = W / CHART_W
sy = H / CHART_H
This maps the fixed CHART_W × CHART_H design coordinate space exactly onto
the current window dimensions, filling every pixel with no letterboxing.
The centering translate is no longer needed and is removed.
chartEl.getScreenCTM().inverse() handles the two-component transform
correctly, so tooltip hit-testing remains accurate at any window shape.
Tooltip boundary clamping still uses CHART_W / CHART_H (chart coordinates).
