- pie menus patterns (#434)
- markup: simple markup language for color change? (#902)
!- font: need handling of missing glyphs by not packing/rasterizing glyph 0 of a given font.
- font: MergeMode: flags to select overwriting or not.
- font: MergeMode: duplicate glyphs are stored in the atlas texture which is suboptimal.
- font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype)
- font: free the Alpha buffer if user only requested RGBA.
!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
- font: a CalcTextHeight() helper could run faster than CalcTextSize().y
@ -252,7 +250,6 @@ It's mostly a bunch of personal notes, probably incomplete. Feel free to query i
- font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
- font/draw: need to be able to specify wrap start position.
- font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines)
- font: imgui_freetype.h alternative renderer (#618)
- font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct).
- font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
- font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
