Fix issue when drawing textured shapes off-screen

When determining whether or not to draw each pixel of a textured line
or rectangle, the modulo-by-eight operation was being performed on a
signed value, which was returning a negative value when the pixel being
drawn was off-screen. When the negative value was then converted to an
unsigned value, the result was close to usize::MAX, and was causing an
out-of-bounds array access.

To fix this, the value is converted to an unsigned value before taking
the modulo.
