Functions
int32_t	tachyon::SnapPx (float v)
	Round half up, the same rule the box shader uses.
IntRect	tachyon::SnapAbsolute (float4 px)
	A box with no snapped parent: each edge to the nearest pixel.
float4	tachyon::PixelBounds (const float3x2 &toPixels, IntRect r)
	The bounds of a rect mapped to window pixels, { x0, y0, x1, y1 }.
IntRect	tachyon::SnapToParent (float4 parentPx, IntRect parentSnapped, float4 childPx)
	A nested box: each edge keeps its rounded distance from the parent's snapped edge on the same side.
