Subject: [PATCH 1002/1003] engine/display: fix count size for sin_table

gcc49 sanitizer found the following error:
../../../hacks/glx/engine.c:659:24: runtime error: index 720 out of bounds for type 'float [720]'
../../../hacks/glx/engine.c:660:24: runtime error: index 720 out of bounds for type 'float [720]'

Since countof() is defined on the head of this source, use this
to count the size of sin_table array correctly.
