* the client to provide a struct of GL function pointers. This struct can be
|
|
* specified per-GrContext as a parameter to GrContext::Create. If NULL is
|
|
* passed to Create then the "default" GL interface is used. If the default is
|
|
* also NULL GrContext creation will fail.
|
|
*
|
|
* The default interface is returned by GrGLDefaultInterface. This function's
|
|
* implementation is platform-specific. Several have been provided, along with
|
|
* an implementation that simply returns NULL. It is implementation-specific
|
|
* whether the same GrGLInterface is returned or whether a new one is created
|
|
* at each call. Some platforms may not be able to use a single GrGLInterface
|
|
* because extension function ptrs vary across contexts. Note that GrGLInterface
|
|
* is ref-counted. So if the same object is returned by multiple calls to
|
|
* GrGLDefaultInterface, each should bump the ref count.
|
|
*
|
|
* By defining GR_GL_PER_GL_CALL_IFACE_CALLBACK to 1 the client can specify a
|
|
* callback function that will be called prior to each GL function call. See
