Is your feature request related to a problem? Please describe. Currently the filament UI doesn't provide options to scale or magnify UI/font.

Describe the solution you'd like I'd like to have control over the size of UI/font for a certain set of sample apps.

These are just sample/test apps, our goal is not to support them like real apps.

In ImGuiHelper.cpp, we can pass a different value via io.Fonts->AddFontFromFileTTF(fontPath.c_str(), 16.0f); to change the font.

To do this dynamically, we may want to call ClearFonts() before readd the font again, which might also have to call ClearTexData() and ClearInputData() from ImFontAtlas.
