Animates text surrounded by rectangle, but text placement is quantized text/plain 2008-06-05 01:26 1.54 KB

Positioning of text using text() rounds coordinates before scaling. This results in very
imprecise text placement when scaling screen space with a factor greater than 1. This does
not occur to other objects (lines, polygons etc.) subject to the same scaling. Rounding also
occurs to the offset implied by textAlign() with parameters other than (LEFT,BOTTOM).

This problem only occurs with the default renderer, although text is of poor quality in
OPEN_GL and P3D.

See my patch for #866; I believe that will fix this, too.
