set up the kernels

read 16bit value and convert to 24bit RGB

find minimum y position if it starts at x1

rects array must be big enough to accommodate all characters in the given ranges

check if a utf8 string contains a prefix which is the utf16 string; if so return length of matching utf8 string

Cubic Bezier takes 4 controls points

Quadratic Bezier takes 3 controls points

UTF16 strings use surrogate pairs to encode codepoints >= 0x10000, so we should save the high surrogate.

Current score encoding (lower is highest priority): - 0: ImGuiInputFlags_RouteGlobalHigh - 1: ImGuiInputFlags_RouteFocused (if item active) - 2:

Helper to snap on edges when aiming at an item very close to the edge, So the difference between WindowPadding and ItemSpacing will be in the visible

If you get an error please report on GitHub. You may try different GL context version or GLSL version.

FIXME: Perhaps we could clear queued events as well?

Compare to detect usage errors

Cursor & Selection

After a user-input the cursor stays on for a while without blinking

Find window given position, search front-to-back FIXME: Note that we have an inconsequential lag here: OuterRectClipped is updated in Begin(), so wind

Window has already passed the IsWindowNavFocusable()

References are only valid until a new value is added to the storage. Calling a Set***() function or a Get***Ref() function invalidates the pointer.

GLFW doesn't allow to distinguish Mouse vs TouchScreen vs Pen. Add support for Win32 (based on imgui_impl_win32), because we rely on _TouchScreen info

Closely mimics PathBezierToCasteljau() in imgui_draw.cpp
