CELayoutEditor--SnapToGrid problem

[kili]

Hi,
I've used the latest version of 0.5b
and found that the child component can't snap to the grid correctly,
but the parent is correct.

May I ask in the EditorCanvas.cpp

what is this line do with '-8'?
y0 = y1 = 1.0f - ((GLfloat)(i * step) / (mCurrentHeight-8 ) * 2.0f);

this seems cause the grid painting wrong,also x.


Another problem, can I use mouse to let
the window snap to the grid when moving?
