fix(flutter): keep the painted cursor hotspot in place when zoom cursor is off

Browse Source 
`CursorPaint` subtracted the hotspot in remote pixels and then scaled it
by the canvas scale, but drew the image at scale 1.0, so the hotspot
landed hotx * (1 - scale) logical pixels away from the remote cursor
position. Cursors with a centered hotspot (I-beam, crosshair) were off
by up to half their size in Adaptive view. Subtract the hotspot after
scaling the position instead.
