GLubyte *readPPM(FILE *fin, GLsizei *wid, GLsizei *ht)
PPM raw format uses no compression. Each color is represented by a
byte for each channel r,g,b. Bytes are assumed to be unsigned.
Space is allocated for the bytes based upon the width and height
read in the file header. For the most portable result with OpenGL
and graphics cards, use power of 2 sizes for width and height.
The width and height read in the header of the ppm image are passed
back into wid and ht. A Null pointer is returned if there was an error
otherwise a pointer to the image bytes is returned.
When finished with the image you should free the allocated space.
only ppm RAW FORMAT is supported by this routine
make sure the file is opened for binary read
