Fix T99459: GPencil: Fill tool on the surface not in the correct place

There is a 1 pixel error in the size registered for the buffer
dimensions.

NOTE: This issue indicates that the texture scale is different from the
region, so the mouse-based coordinates used are actually misaligned.
This misalignment will be fixed in another commit.

Regression probably introduced in rB1d49293b8044 + rB45f167237f0c8
