per font size instance there is a glyph cache - BUT now i'd need to handle per
size AND transform (scale h AND v). i'd either need a glyph cache per one of
these or change the glyph hash key to include the transform (scaling factors).
the REAL problem here is the fact that truetype doesn't always like to scale
linearly as u'd like - it may want to round off/align itself to a particular
pixel boundary and so the text layout you chose before wont necessarily match :)

true - font loading each time would be expensive :)

true true :) though evas was never designed for printing - it is capable in
design/theory of doing it :)

let me look... aah i see. there is a problem with your patch... here's why -
what If you scale horizontally more than vertically? you use a single multiplier
for size when the size scaling would be different in each direction (horizontal
and vertical) - that's why i went and resorted to bitmap scaling to get that
right :) at least the bitmap scaling gets the font to be the right size/display
at the right aspect, but does lose quality :(
