f1fd23cf32 common render: removed unnecessary assignments in update() fun 
The rotation part of the transformation matrix can be assigned,
it does not have to be multiplied by the identity matrix.
The values of e13 and e23 of the transformation matrix represents the translation,
so they don't need to be taken into account in the rotation part.

e9939dec82 common canvas: fix non-updated paints. 
When shapes are poped from canvas while retaining shapes instances,
they have no chances to redraw after pushed again due to missing flag.

This patch fixes it by forcely updating flag on pushing time.
