WriteBrushPixel(id, x, y, color[, trans])
idat the position specified in the first two arguments. If the optional argument
transis specified and the brush has a mask or an alpha channel, then the value specified in the optional argument is written to the transparency channel of the brush. If the brush has a mask,
transmay be set to 0 or 1, and if the brush has an alpha channel, then
transmust be in the range of 0 to 255.
You can also write pixels to brushes by selecting the brush as the output device
using SelectBrush() and then call the Plot() function. Using
however, is faster for most cases because it allows you to modify color and transparency
channels at the same time and you can also avoid the overhead that is generated
by calling SelectBrush() and EndSelect().
