60b25615fd Add _cogl_egl_texture_2d_new_from_image API
This adds an internal texture_2d constructor that can wrap an EGLImage
as a CoglTexture2D. The plan is to utilize this for texture-from-pixmap
support with EGL as well as creating textures from wayland buffers.

d0739ca0ba GL_IMG_TEXTURE_NPOT extension enables TEXTURE_NPOT features on GLES
Older drivers for PowerVR SGX hardware have the vendor-specific
GL_IMG_TEXTURE_NPOT extension instead of the
functionally-equivalent GL_OES_TEXTURE_NPOT extension.

392cfb493a cogl-gles: Check for the GL_ANGLE_framebuffer_blit extension
This extension is the GLES equivalent of the GL_EXT_framebuffer_blit
extension except that it has some extra restrictions. We need to check
for some extension that provides glBlitFramebuffer so that we can
unconditionally use ctx->drv.pf_glBlitFramebuffer in both GL and GLES
code. Even with the restrictions, the extension provides enough
features for what Cogl needs.

4f08e3cf6e cogl-buffer: Support mapping buffers for write on GLES
GLES has an extension called GL_OES_mapbuffer to support mapping
buffer objects but only for writing. Cogl now has two new feature
flags to advertise whether mapping for reading and writing is
supported. Under OpenGL, these features are always set if the VBO
extension is advertised and under GLES only the write flag is set if
the GL_OES_mapbuffer extension is advertised.

eb179d4b67 build: Start moving to a non-recursive layout
*** WARNING: THIS COMMIT CHANGES THE BUILD ***

Do not recurse into the backend directories to build private, internal
libraries.

We only recurse from clutter/ into the cogl sub-directory; from there,
we don't recurse any further. All the backend-specific code in Cogl and
Clutter is compiled conditionally depending on the macros defined by the
configure script.

We still recurse from the top-level directory into doc, clutter and
tests, because gtk-doc and tests do not deal nicely with non-recursive
layouts.

This change makes Clutter compile slightly faster, and cleans up the
build system, especially when dealing with introspection data.

Ideally, we also want to make Cogl part of the top-level build, so that
we can finally drop the sed trick to change the shared library from the
GIR before compiling it.

Currently disabled:

  ‣ OSX backend
  ‣ Fruity backend

Currently enabled but untested:

  ‣ EGL backend
  ‣ Windows backend
