+
+## BulbNormalMapClear
+
+`BulbNormalMapClear()`
+
+**Returns:** N/A (`undefined`)
+
+|Argument|Datatype|Purpose|
+|--------|--------|-------|
+|None    |        |       |
+
+Clears a normal map surface, resetting all pixels to "flat" i.e. the normal for that pixel will be set to `(0,0,1)`, a vector that points straight upwards.
+
+ 
+
+## BulbNormalMapShaderSet
+
+`BulbNormalMapShaderSet([forceFlat=false])`
+
+**Returns:** N/A (`undefined`)
+
+|Argument     |Datatype|Purpose                                                                             |
+|-------------|--------|------------------------------------------------------------------------------------|
+|`[forceFlat]`|boolean |Whether subsequent draw calls should be forced to draw "flat" data to the normal map|
+
+Before drawing normal map graphics to a renderer's normal map surface using Bulb's native functions (see below) you must call this function. If the `forceFlat` parameter is set to `true` then all draw calls will be forced to "flat" i.e. the normal will be set to `(0,0,1)`, a vector that points straight upwards.
+
+ 
+
+## BulbNormalMapShaderReset
+
+`BulbNormalMapShaderReset()`
+
+**Returns:** N/A (`undefined`)
+
+|Argument|Datatype|Purpose|
+|--------|--------|-------|
+|None    |        |       |
+
+Resets ("un-sets") the Bulb normal map shader.
+
+ 
+
+## BulbNormalMapDrawSelf
+
+`BulbNormalMapDrawSelf([spriteIndex])`
+
+**Returns:** N/A (`undefined`)
+
+|Argument       |Datatype    |Purpose                                                                                 |
+|---------------|------------|----------------------------------------------------------------------------------------|
+|`[spriteIndex]`|sprite index|Sprite to draw. If not specified, the instance's current sprite (`sprite_index`) is used|
+
+Analogous to GameMaker's native `draw_self()` function.
+
+?> You should set Bulb's normal map shader before executing this function by calling `BulbNormalMapShaderSet()` beforehand.
+
+ 
+
+## BulbNormalMapDrawSprite
+
+`BulbNormalMapDrawSprite(sprite, image, x, y)`
+
+**Returns:** N/A (`undefined`)
+
+|Argument|Datatype    |Purpose                         |
+|--------|------------|--------------------------------|
+|`sprite`|sprite index|Sprite to draw                  |
+|`image` |number      |Image of the sprite to draw     |
+|`x`     |number      |x position to draw the sprite at|
+|`y`     |number      |y position to draw the sprite at|
+
+Analogous to GameMaker's native `draw_sprite()` function.

+
+## BulbNormalMapDrawSpriteExt
+
+`BulbNormalMapDrawSpriteExt(sprite, image, x, y, xScale, yScale, angle)`
