#18286: Region plot fails when there is equation condition
------------------------+-------------------------------
Reporter: yzh | Owner:
Type: defect | Status: new
Priority: major | Milestone: sage-6.7
Component: graphics | Keywords: region_plot

------------------------+-------------------------------
region_plot can't deal with equations. For example the condition `x == 0`
is treated as `x < 0`.
{{{
sage: x, y = var('x, y')
sage: region_plot([x == 0], (x, -1, 1), (y, -1, 1))
sage: region_plot([x^2+y^2==1, x<y], (x, -1, 1), (y, -1, 1))
}}}
