I was also surprised but drawText shows up as the first cost centre on the yi.prof I attached to comment 13 on the #265 bug report. I found that removing functionality from drawText made a noticeable impact on drawing speed, compiling without debugging and profiling. This was a couple of months ago; I'll try to do some better tests when I have some free time. --~--~---------~--~----~------------~-------~--~----~ Yi development mailing list yi-devel@googlegroups.com http://groups.google.com/group/yi-devel -~----------~----~----~----~------~----~------~--~---
