int PgDrawPixel( PhPoint_t const *pt );
int PgDrawIPixel( int x,
int y );
int PgDrawPixelCx( void *dc,
PhPoint_t const *pt );
int PgDrawIPixelCx( void *dc,
int x,
int y );
ph
These functions build a command in the draw buffer to draw a pixel.
For PgDrawPixel*(), the pt argument points to a
PhPoint_t
structure that defines the pixel
location;
for PgDrawIPixel*(), x and y specify the
location.
PgDrawPixel() and PgDrawIPixel() work on the current
draw context, while you can specify the draw context dc for
PgDrawPixelCx() and PgDrawIPixelCx().

- The draw buffer is too small to hold the current draw state,
the draw command, and the data. Increase the size of the draw buffer.
