p_min = upper-left, p_max = lower-right Note we don't render 1 pixels sized rectangles properly.

This is one of the very rare legacy case where we use ImGuiWindow methods, it should ideally be flattened at some point but it's been used a lots by w

Helpers: Bit manipulation

Zero-terminated string hash, with support for ### to reset back to seed value. e.g. "label###id" outputs the same hash as "id" (and "label" is general

Similar to resize(0) on ImVector: empty string but don't free buffer.

make the selection/cursor state valid if client altered the string

the edge passed in here does not cross the vertical line at x or the vertical line at x+1 (i.e. it has already been clipped to those)

FIXME-DPI: I don't want to formalize this just yet. Because reasons. Please don't use.

Buf is zero-terminated, so end() will point on the zero-terminator

@OPTIMIZE: binary search

Generally for non-user facing functions: assert on invalid ID.

0: East, 3: South, 6: West, 9: North, 12: East

update selection and cursor to match each other

Find glyph, load if necessary, return fallback if missing

Find beginning-of-line

Avoid naming collision with imgui_demo.cpp's HelpMarker() for unity builds.

std::lower_bound but without the bullshit
