[Lcdproc] MtxOrb problem

[Michelle Dupuis]

I'm using the Oct 4 nightly build - so I should have recent code.  

I tried the test program - and strange characters appear.  In one case a
heart overlayed into a white box, etc.  There is still some strange flicker.
(perhaps this is not simply an overwrite / scroll problem).

Entirely possible, but that's all client-dependent.

Are you sure you have the latest version of LCDproc? (some nightly
after 01-Oct)  I fixed a bug in MtxOrb.c that caused custom chars to
be displayed one line below and one char to the right from where they
should be (there was a missing 'x--' and 'y--' in MtxOrb_chr that
caused the accidental offset).  That could certainly cause all sorts
of overrun problems.

Here's the 2-line bargraph test client.  If you _are_ having
off-by-one problems with custom chars, this client won't look good
either, but it _is_ a 2-line client.
