<div>BTW, in case anyone is curious, here is how matrices look
when printing them on a workspace with cmd-p. I draw matrices
over the binary field in a special way (first screenshot), and
I scale them down if they are too big.</div>
<div>I did this because it was hard to make matrices look good
when printing them as text, so instead I draw them on a form
and embed the form when printing them. I only do this with
matrices, they are especially problematic when printing
because they print with more than one line, they are the only
objects in my system that need more than one line for
printing. When I printed them as text with more than one line,
printing a list of matrices (for example an array of matrices,
as in the example where I print a basis of a vector space in
the screenshots) they would look horrible. Now a list of
matrices is printed in a single line as expected, and the
point size of the enclosing parentheses is adjusted
automatically (I have messages
Stream>>#withParentheses:, #withBrackets:,
#withAngleBrackets:, etc, that do this automatically).</div>

It looks beautiful!<br>

<div>I still have two little problems that I might want to
tweak:</div>
<div>1) the parentheses are too thick, setting the point size is
not the right thing to do, maybe we need a new text attribute
for scaling text without changing the point size?;</div>

The easiest solution is to use a different font, just for the
parentheses. For example, NeoEuler parentheses are much lighter at
large point sizes.<br>

<div>2) matrices inside matrices loose the transparent
background, the background becomes black, as you see in the
example in the second screenshot.<br>

I guess this should be fixable. If you can prepare an image with
such example for me to play with, I'll give it a try. For example
(not sure if related) VectorEngine can do blending over translucent
backgrounds, but only if subpixel sampling is used. I know, there is
no relation between these two features... But I wanted to keep
options to a small number, and usually we only use cheaper whole
pixel AA and cheaper alpha blending that can't blend over
translucent backgrounds. So, maybe just using the SubPixel engine
solves this problem, or I'll be happy to take a look.<br>

<div>This change set fixes a little bug in VectorCanvas that
cames up when using the canvas to draw text with images on
a form (outside morphic). I do this to draw matrices, and
when drawing a matrix whose coefficients are also matrices
this came up. The fix is simply checking that the world is
not nil.<br>
