How can I adjust the tooltip font size?

[thadguidry]

I am using standalone Cardinal.
I really could use a larger tooltip size, especially while hovering over modules in the module browser. But also throughout Cardinal standalone.

I looked in native.json and only saw "tooltips": true.
I was hoping for something like a "tooltipsZoom": [0..400] ???

It does look like popups or tooltips can utilize ui scaling as shown in Sassy Scope? but Cardinal Standalone doesn't handle this currently?

Lines 509 to 510 in 959356f

	ImGui::BeginTooltip();
	int note = (int)(12 * log(32 * POW_2_3_4TH * (freqbins[(int)(mp.x / uiScale)] / (sizef-1))) / log(2));

Lines 663 to 668 in 959356f

	// Tooltips
	// - Tooltip are windows following the mouse. They do not take focus away.
	IMGUI_API void BeginTooltip(); // begin/append a tooltip window. to create full-featured tooltip (with any kind of items).
	IMGUI_API void EndTooltip();
	IMGUI_API void SetTooltip(const char* fmt, ...) IM_FMTARGS(1); // set a text-only tooltip, typically use with ImGui::IsItemHovered(). override any previous call to SetTooltip().
	IMGUI_API void SetTooltipV(const char* fmt, va_list args) IM_FMTLIST(1);

DearImGui code is only used for Sassy Scope and Ildaeil module UIs.

This would need a change of how the Rack engine renders (and configures) the tool-tips.
Ideally it would be an option that is added upstream though.
