Apply objectLimit across filtered graphics groups

[haocyan0723-code]

/claim #42

This keeps the filtering step as-is, then applies one shared objectLimit across the visible object groups instead of slicing each group separately.

Why this matters:

• objectLimit={3} no longer allows 3 lines plus 3 rects plus 3 points.
• The red warning still uses the pre-limit filtered count, so it shows when the view was actually capped.

Checked:

• Confirmed the branch file no longer slices each object group by objectLimit.
• Confirmed rendering now uses the visible limited groups.
