Store reading and writing to `.offsets`.

Avoid mutations to `.drawcalls` from outside the `BufferGeometry`.

Replace `geom.offsets.push` / `geom.drawcalls.push` with
`geom.addDrawCall()` everywhere.

Added class WebGLProperties, webgl properties now stored in that class. Checks for uuids and existance of properties encapsulated in this class

eg. / e.g.
vertice / vertex
fullframe / full-frame
todo / TODO
unreckognized / unrecognized
ontop / in front
initialise / initialize
unforms / uniforms
overriden / overridden
interpolatation / interpolation
subsurve / sub-curve
Catmull-rom / Catmull-Rom
consruct / construct
colinear / collinear
perpenicular / perpendicular
minimim / minimum
segements / segments
speficied / specified
compatable / compatible
egde / edge
initalization / initialization
shiftet / shifted
childrens' / children's
ambigious / ambiguous
barycoordinates / barycentric coordinates
equi distance / equidistant
equidistance / equidistant
ist / is

And remove one `console.log`

@benadams Oh wait, is this because the strides stuff?
