Sets the drawing target for rasterization.
This function specifies the drawing target where the rasterization will occur. It can target a specific framebuffer object (FBO) or the main surface.
| [in] | id | The GL target ID, usually indicating the FBO ID. A value of 0 specifies the main surface. |
| [in] | w | The width (in pixels) of the raster image. |
| [in] | h | The height (in pixels) of the raster image. |
id) is set to 0, the operation will be aborted.
