ImFont: Renamed ImFont::Glyph to ImFontGlyph (for consistency and so ImFontAtlas types can use it without ordering half of the file). Left a redirection type.

boolPixelSnapH;// false // Align every glyph to pixel boundary. Useful e.g. if you are merging a non-pixel aligned font with the default font. If enabled, you can set OversampleH/V to 1.
ImVec2GlyphExtraSpacing;// 0, 0 // Extra spacing (in pixels) between glyphs. Only X axis is supported for now.
ImVec2GlyphExtraSpacing;// 1, 0 // Extra spacing (in pixels) between glyphs. Only X axis is supported for now.
ImVec2GlyphOffset;// 0, 0 // Offset all glyphs from this font input.
constImWchar*GlyphRanges;// NULL // Pointer to a user-provided list of Unicode range (2 value per range, values are inclusive, zero-terminated list). THE ARRAY DATA NEEDS TO PERSIST AS LONG AS THE FONT IS ALIVE.
boolMergeMode;// false // Merge into previous ImFont, so you can combine multiple inputs font into one ImFont (e.g. ASCII font + icons + Japanese glyphs). You may want to use GlyphOffset.y when merge font of different heights.
