ev->keyboard.modifiers seems always zero so using that...

OpenGL3 Render function. Note that this implementation is little overcomplicated because we are saving/setting up/restoring every OpenGL state explici

Also destroy old swap chain and in-flight frames data, if any.

Register a texture FIXME: This is experimental in the sense that we are unsure how to best design/tackle this problem, please post to https://github.c

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
