#666's minor gridlines stepped in value units, but #669 scales a log axis in
exponents of its base; map each minor step back through the base.

#662 gives scatter and bubble charts one x scale over every series; #603's
trendlines still mapped x over each series' own extent, so a fit drifted off
its points. Use the chart's x scale where there is one.

#640 orders category slots bottom-to-top on horizontal bars (or reversed via
c:orientation) while #603 pads the axis for trendline forecasts. Slots now
include the forecast padding on the right side, and trendlines map their
category positions through the same slot order as the bars.

f64::clamp panics when the plot is narrower than the caption's minimum width;
use main's clamp_soft, as the rest of the chart code now does.

Make the slide show behave like PowerPoint for interactive decks.
- Hit testing resolves the topmost visible shape under the pointer.
Non-interactive shapes block shapes beneath them; the hand cursor
shows only over interactive shapes.
- Click-triggered animations (interactive sequences) play on shape
click, repeat after their last step, and apply in click order so
cycling "score ring" shapes work.
- Each slide keeps its own progress: returning to a slide through a
link or Back restores hidden shapes and animation state.
- A shape with a link and an animation follows the link immediately;
its animation clock only runs while the slide is shown and resumes
with the remaining time on return.
- With advance-on-click off, background clicks still play animation
steps but never change slide.
- A click on a playing step completes it at once.
Docs (gaps, animation and slide show parity, roadmap) are updated.

DrawCurve, DrawClosedCurve and FillClosedCurve (GDI+ cardinal splines, the
smoothed lines of charts and freehand shapes) draw as cubic Béziers with
the record's tension, offset and segment count; FillRegion fills the region
object's area. These records were skipped, so the shapes were missing.

Radar and filled radar charts are drawn polar: spokes per category,
polygon gridlines and value labels up the first spoke. Stock charts
draw high-low lines with close dashes, or up/down bars between open
and close, and are saved as c:stockChart (hiLowLines, upDownBars)
instead of a line chart; c:upDownBars is read, and chart.options takes
upDownBars. New stock charts start as high-low-close and new combo
charts as columns with a line.

Read the regionMap chartEx layout as a RegionMap chart (regions and
their colour values), write the part back as read while unchanged, and
when edited rebuild it with the original geography (projection, culture
and cached boundaries) carried over. With no map data in the repo, the
renderer draws each region as a value-coloured tile with a colour scale
and a note that the map itself is not drawn.
