[Feature request] Changing the font size

[vitaliylag]

The font size of suggestions and other Japanese text is too small. It would be great to add an option to choose the font size.

Before jumping into a solution, can we discuss a bit more on

• what's the common way to adjust font size (or logical DPI) with the attached screens in your platform?
• how mozc_renderer can access to the system level font settings programmatically?

As far as I know, the system level DPI setting is already taken into account at least in Windows so I guess you are using Mozc in some other platform, right? If so, do you happen to know how mozc_renderer can access to the system level font settings (or DPI settings) programmatically?

mozc/src/renderer/renderer_style_handler.cc

Lines 206 to 225 in f79e092

	void RendererStyleHandler::GetDPIScalingFactor(double *x, double *y) {
	#ifdef _WIN32
	WTL::CDC desktop_dc(::GetDC(nullptr));
	const int dpi_x = desktop_dc.GetDeviceCaps(LOGPIXELSX);
	const int dpi_y = desktop_dc.GetDeviceCaps(LOGPIXELSY);
	if (x != nullptr) {
	*x = static_cast<double>(dpi_x) / kDefaultDPI;
	}
	if (y != nullptr) {
	*y = static_cast<double>(dpi_y) / kDefaultDPI;
	}
	#else // _WIN32
	if (x != nullptr) {
	*x = 1.0;
	}
	if (y != nullptr) {
	*y = 1.0;
	}
	#endif // !_WIN32
	}

I think that Font size is small , too.

I want to change font family also.
Some character has very similar shape for other one, like 1 (one) and l ( small letter of L ).
I do not need UI dialog for change it. Editing the preference file directly may be acceptable.
