Jonas Ådahl 5d83260b19 actor: Fix transforming stage point when scale is less than 1 
The commit 6cd24faaa5 (actor: Clean up
transform_stage_point()) changed the validation of the transformation
matrix to ignore the fraction part of the determinant. This caused
clutter_actor_transform_stage_point() to fail and return FALSE for
actors which scale was less than 1.

Previously the validation was ('det' being a float):
	det = (RQ[0][0] * ST[0][0])
	    + (RQ[0][1] * ST[0][1])
	    + (RQ[0][2] * ST[0][2]);
	if (!det)
		return FALSE;

Semantically, the if statement expression '!det' is equivalent to
'det == 0', i.e. 'det == 0.0f'. Post cleanup patches, 'det' was turned
into a double, and the if statement was changed to:

	if (CLUTTER_NEARBYINT (det) == 0)
		return FALSE;

which, different from before, rounds the determinant to the nearest
integer value, meaning determinant in the range (-0.5, 0.5) would be
considered invalid.

This patch reverts this part to the old behavior, while, because of the
inexact nature of floating point arithmetics, allowing a bit more liberal
meaning of "equals to 0" than '== 0.0'.
