@OPTIMIZE: primary accumulator for huffman expand the buffer to as many bits as possible without reading off end of packet it might be nice to allow f

traverse the layout to locate the nearest character to a display position

discard the oldest entry in the undo list

find the x/y location of a character, and remember info about the previous row in case we get a move-up event (for page up, we'll have to rescan)

canoncialize the selection so start <= end

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

Use case A: Begin() called from constructor with items_height<0, then called again from Sync() in StepNo 1 Use case B: Begin() called from constructor

Calculations consist of several orthogonal steps that compose multiplicatively: * * First, we compute the attenuations (volume and LFE) due to dista

ComputeInnerRadiusDiffusionFactors is a utility function that returns how * energy dissipates to the speakers, given the radial distance between the
