Sets the spotlight light direction. You must use SetLightType to set the light type to SOURCE_TYPE_POINT. This function is an immediate function. (Immediate functions directly generate commands and insert them into the command buffer.)

The format of the data inserted into the command buffer is:
0x00000000 (Y << 16) | X
0x00000004 [Reserved]
0x00000008 Z
0x0000000c [Reserved]

The X,Y, and Z components are signed 13-bit fixed point values with an 11-bit fractional portion. This function converts from 32-bit to a signed 13-bit fixed point value with an 11-bit fractional portion format.

The default value is all 0.0f.
