GFX_LayerFromOrientedSpace 

Transforms a layer oriented space to screen space. 

 

GFX_LayerPointFromOrientedSpace 

Transforms a point from oriented space to screen space given a layer, a display orientation, and a mirroring setting. 

 

GFX_LayerPointToOrientedSpace 

Transforms a point from screen space to oriented space given a layer, a display orientation, and a mirroring setting. 

 

GFX_LayerReadBuffer 

Gets the pointer to the layer's current read pixel buffer. 

 

GFX_LayerRectFromOrientedSpace 

Transforms a layer point from oriented space to screen space given a layer, a display orientation, and a mirroring setting. 

 

GFX_LayerRectToOrientedSpace 

Transforms a rectangle from screen space to oriented space given a layer, a display orientation, and a mirroring setting. 

 

GFX_LayerRotate 

Swaps the width and height dimensions of a layer. Can be used for run-time display orientation 

 

GFX_LayerSwap 

Performs a swap operation on the given layer. This advances the pointers of layer's buffer chain. The current write buffer becomes the new read buffer and a new buffer is chosen as the new write buffer. Has no effect in single buffer environments. 

 

GFX_LayerToOrientedSpace 

Transforms a layer from screen space to oriented space. 

 

GFX_LayerWriteBuffer 

Gets the pointer to the layer's current write pixel buffer.

GFX_FrameBuffer_t 

A frame buffer is a wrapper around a pixel buffer construct that is used by display drivers to manage frame buffers. 

 

GFX_Layer_t 

Layers describe basic display drawing areas and are meant to map directly to graphics controller hardware layers.
