N/A（无返回值）

描述

This function resets the draw target and should be called when you no longer wish to use the current shader (set using shader_set).

重要！该函数在试用版（Trial License）产品中不可用。

例如：

shader_set(shader_Glass);
draw_self();
shader_reset();

The above code will set a shader top be used for drawing, then draw the current sprite used for the instance using it.
