Register the rectangles we need for the rounded corner images

Generate the actual pixel data for rounded corners in the atlas

Gamepad navigation mapping

Map VK_xxx to ImGuiKey_xxx.

Sanitize format - Zero terminate so extra characters after format (e.g. "%f123") don't confuse atof/atoi - stb_sprintf.h supports several new modifier

- For scanning we need to remove all width and precision fields and flags "%+3.7f" -> "%f". BUT don't strip types like "%I64d" which includes digits.

Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return "" fmt = "%.3f" -> return fmt fmt =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib

Find end-of-line. Return pointer will point to either first \n, either str_end.

Find the shortest single replacement we can make to get the new text from the old text. Important: needs to be run before TextW is rewritten with the

4 bytes-per-pixel

API is designed this way to avoid exposing the 4K page size e.g. use with IsGlyphRangeUnused(0, 255)

Bias scoring rect ahead of scoring + update preferred pos (if missing) using source position

Closely mimics ImBezierCubicClosestPointCasteljau() in imgui.cpp

Note: as with every ImDrawList drawing function, this expects that the font atlas texture is bound.
