Added a test for eglGetProcAddress and dispatching for EGL and GL functions. Added three EGL extension functions to the EGL dummy vendor, to test dispatching extensions by display, device, and current context. Added a simple implementation of eglCreateContext, eglDestroyContext, and eglMakeCurrent, and glGetString.

/**

|
|
*
|
|
* Some declarations for the dummy vendor library used to test libEGL.
|
|
*
|
|
* For the EGL tests, we create two vendor libraries. They're both identical,
|
|
* except that each one has its own vendor name string.
|
|
*
|
|
* The vendor name is returned for things like the EGL_VENDOR and GL_VENDOR
|
|
* strings, so that we can check that an EGL or GL call gets dispatched to the
|
|
* right vendor.
|
|
*
|
|
* In addition, you can pass the vendor name as the native display handle to
|
|
* eglGetPlatformDisplay, with EGL_DUMMY_PLATFORM for the platform type. That
|
|
* mainly provides an easy way to create an EGLDisplay without having to mess
|
|
* around with EGLDeviceEXT handles.
|
|
*
|
|
* Using EGL_DUMMY_PLATFORM also tests whether libEGL.so can deal with a call
|
|
* to eglGetPlatformDisplay with an unknown platform, since it does have
|
|
* special handling for EGL_PLATFORM_DEVICE_EXT.
