When using manual min and max for an axis, ticks are sometimes not
correctly placed. The gog_axis_view_render function assumes that the firs
tick is at the beginning of the axis and the last at the end, but this is
not always the case. The following example, will make things clear, I hope:
Type 0 in A1 and B1, 10 in A2 and B2
Select the four cells and insert a xy chart, then change the min and max
values of one of the axis to, respectively, -0.2 and 10.2.
The axis labels are -0.2, 1.8,... 9.8.
On the graph 10 is smaller than 9.8!
I think that the labels should remain round values (0,2,...10) and the
ticks moved appropriately.
