Internal method for releasing all temporary buffers which have been allocated using BLT_AUTOMATIC_RELEASE; is called by OGRE.
forceFreeUnused | If true , free all unused temporary buffers. If false , auto detect and free all unused temporary buffers based on temporary buffers utilization. |

Allocates a copy of a given vertex buffer.
sourceBuffer | The source buffer to use as a copy. |
licenseType | The type of license required on this buffer - automatic release causes this class to release licenses every frame so that they can be reallocated anew. |
licensee | Pointer back to the class requesting the copy, which must implement HardwareBufferLicense in order to be notified when the license expires. |
copyData | If true , the current data is copied as well as the structure of the buffer/ |

The update shall be triggered by GpuProgramParameters, if is dirty

Create a hardware index buffer.
itype | The type in index, either 16- or 32-bit, depending on how many vertices you need to be able to address |
numIndexes | The number of indexes in the buffer |
usage | One or more members of the HardwareBuffer::Usage enumeration. |
useShadowBuffer | If set to true , this buffer will be 'shadowed' by one stored in system memory rather than GPU or AGP memory. You should set this flag if you intend to read data back from the index buffer, because reading data from a buffer in the GPU or AGP memory is very expensive, and is in fact impossible if you specify HBU_WRITE_ONLY for the main buffer. If you use this option, all reads and writes will be done to the shadow buffer, and the shadow buffer will be synchronised with the real buffer at an appropriate time. |

This type of buffer allows the upload of shader constants once, and sharing between shader stages or even shaders from another materials. The update shall be triggered by GpuProgramParameters, if is dirty

Create a hardware vertex buffer.
vertexSize | The size in bytes of each vertex in this buffer; you must calculate this based on the kind of data you expect to populate this buffer with. |
numVerts | The number of vertices in this buffer. |
usage | One or more members of the HardwareBuffer::Usage enumeration; you are strongly advised to use HBU_STATIC_WRITE_ONLY wherever possible, if you need to update regularly, consider HBU_DYNAMIC_WRITE_ONLY and useShadowBuffer=true. |
useShadowBuffer | If set to true , this buffer will be 'shadowed' by one stored in system memory rather than GPU or AGP memory. You should set this flag if you intend to read data back from the vertex buffer, because reading data from a buffer in the GPU or AGP memory is very expensive, and is in fact impossible if you specify HBU_WRITE_ONLY for the main buffer.
