Add Greek glyph range to ImFontAtlas #5676

I'm working on an scientific computing application that makes fairly heavy use of Greek letters in the UI.

It would be convenient if ImFontAtlas had a GetGlyphRangesGreek() method so I didn't have to add every Greek letter to the atlas manually.

Feel free to make a PR for it, thank you.

I don't have a fork handy that I can push to and have some other things to work on.

But the Greek and Coptic Unicode range is U+370 to U+3FF. Here's what I have in my code now.

for(wchar_t i=0x370; i<=0x3ff; i++)	//Greek and Coptic
	builder.AddChar(i);

How about U+1F00 Greek Extended, what is that useful for ?

I'm not sure as I don't actually speak the Greek language, I just use the letters in math :)

What about adding a GreekFull glyph range, similar to what you have with Chinese, that adds that range as well as the base one?

Thanks for the PR. I think i'll merge as is for now, I prefer getting feedback on incomplete ranges.
(Anyhow hopefully those functions will eventually be gotten rid of..)

Author: ocornut <omarcornut@gmail.com>

    Renamed and merged keyboard modifiers key enums and flags into a same set:. ImGuiKey_ModXXX -> ImGuiMod_XXX and ImGuiModFlags_XXX -> ImGuiMod_XXX. (ocornut#4921, ocornut#456)

    Changed signature of GetKeyChordName() to use ImGuiKeyChord.
    Additionally SetActiveIdUsingAllKeyboardKeys() doesn't set ImGuiKey_ModXXX but we never need/use those and the system will be changed in upcoming commits.

    Renamed and merged keyboard modifiers key enums and flags into a same set:. ImGuiKey_ModXXX -> ImGuiMod_XXX and ImGuiModFlags_XXX -> ImGuiMod_XXX. (ocornut#4921, ocornut#456)

    Changed signature of GetKeyChordName() to use ImGuiKeyChord.
    Additionally SetActiveIdUsingAllKeyboardKeys() doesn't set ImGuiKey_ModXXX but we never need/use those and the system will be changed in upcoming commits.
