Elias Naur	3ae5a37c24	gpu,gpu/gl: introduce Backend ... A recent change made the OpenGL functions an interface of the functions required for the implementation of GPU, a renderer for Gio operations. That allowed for running Gio on external systems where OpenGL is available. However, to allow for non-OpenGL flavored backends such as Vulkan, Metal and Direct3D, this change introduces Backend for the high-level operations required by GPU. This change also adds a concrete backend to package gl. Type Backend is a first cut heavily based on OpenGL. Future changes will add more backends, where the Backend interface quite possibly will need refinement. Signed-off-by: Elias Naur <mail@eliasnaur.com>	2020-02-10 18:22:57 +01:00
