Includes the new TRIM$ function
TRIM$(source$ [,mask$] [,where/where$])
This function can remove characters from the beginning or end of a string or both
source$ is the input string
mask$ is a string containing a list of character to be removed. If omitted it defaults to space
where/where$ can be L, R, or B or a string beginning with L, R, or B to specify characters should be removed from the left of the source, the right of the source or both. If omitted defaults to L
Enhancement to 3D modelling
Rendering of the 3D object works by Painters algorithm. This works by sorting the faces and drawing those further away first. In addition the MMBasic firmware supports "back face culling". This doesn't draw faces that are pointing away from the camera. In order to sort the faces the current MMbasic code uses the Z axis position of the face centroid. This works in many situations but in some 3D models it is better to use the furthest vertex and sort on that. I've added that as an option to DRAW3D SHOW and DRAW3D WRITE
DRAW3D SHOW n, x, y, z [,nocull][,usefurthest]
DRAW3D WRITE n, x, y, z [,nocull][,usefurthest]
DRAW3D WRITE n, x, y, z [,nocull][,usefurthest]
set 1 to use the furthest vertex and zero (default) to use the centroid.
