Ah, ok. So the confusion for me was the docs that say:
Code:
Draws a string at gfx_x, gfx_y
...
In REAPER 5.30+, flags,right,bottom can be specified to control alignment:
flags&1: center horizontally
I assumed "center horizontally" meant "center around gfx_x".
That is, when flags,right,bottom are specified, it's no longer the case that it "draws a string at gfx_x, gfx_y", but instead draws centered within the rectangle described by x,y right,bottom.
And yeah I guess the gfx_x/y addition being required is a bug? -- not required, not a bug
