<spi>.init

format = spi.PBUFFER

The pixel format to use when rendering the spherical projection. Can be one of the following values:

Pixel formats
spi.BACKBUFFER	Render to back buffer
spi.PBUFFER	Render to pixel buffer
spi.TEXTURE	Render to texture
spi.AUTO	Automatically determine best rendering surface

This function creates and initializes the SPI rendering context and must precede the use of any other SPI
functions. The SPI related environment variables are read and the default values are set in the SPI context.
It also calls the initialization of the intermediate textures. This function must be used to create a SPI
rendering context, which is then used in all subsequent SPI calls.

NOTE: When using the spi library, some features will not work as expected including the following:

GUI objects (buttons,sliders,etc..)
Objects attached to the SCREEN or HEAD
Subwindows
Framerate display

IMPORTANT: This command must be called after viz.go()
