*
|
* This class represents the minimum set of functionality for a platform
|
* port.
|
*
|
* In addition to implementing Platform class, main entry point must be
|
* created that takes care of parsing command line, creating log and
|
* executing tcu::App. See tcuMain.cpp for reference on implementing
|
* application stub.
|
*
|
* If the platform uses standard posix-style main() for application entry
|
* point, tcuMain.cpp can be used as is. In that case you only have to
|
* implement createPlatform().
|
*
|
* API-specific platform interfaces (glu::Platform and eglu::Platform)
|
* can be provided by implementing get<API>Platform() functions.
