8012eee31f Add _cogl_texture_get_type()
This adds an internal function to get the type of the underlying
hardware texture for any CoglTexture. It can return one of three
values to represent 2D textures, 3D textures or rectangle textures.
The idea is that this can be used as a replacement for
cogl_texture_get_gl_texture when only the target is required to make
it a bit less GL-centric. The implementation adds a new virtual
function which all of the texture backends now implement.

The enum is in a public header because a later patch will want to use
it from the CoglPipeline API. We may want to consider making the
function public too later.

92c3063014 framebuffer: Add cogl_framebuffer draw methods
This adds cogl_framebuffer_ apis for drawing attributes and primitives
that replace corresponding apis that depend on the default CoglContext.
This is part of the on going effort to adapt the Cogl api so it no
longer depends on a global context variable.

All the new drawing functions also take an explicit pipeline argument
since we are also aiming to avoid being a stateful api like Cairo and
OpenGL. Being stateless makes it easier for orthogonal components to
share access to the GPU. Being stateless should also minimize any
impedance miss-match for those wanting to build higher level stateless
apis on top of Cogl.

Note: none of the legacy, global state options such as
cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or
cogl_program_use() are supported by these new drawing apis and if set
will simply be silently ignored.

ec1bb4ce39 When internally using an FBO, check for allocation errors
Both the cogl_texture_get_data and _cogl_blit_begin implementations
will internally try to create an FBO for a texture and have fallbacks
if the FBO fails. However neither of them were catching errors when

This patch just adds an explicit call to cogl_framebuffer_allocate for
these uses and causes it to use the next fallback if it fails.

d42f1873fc framebuffer: Flush the journal on destruction
Instead of flushing the journal whenever the current framebuffer on a
context is changed it is now flushed whenever the framebuffer is about
to be destroyed instead. To do this it implements a custom unref
function which detects when there is going to be exactly one reference
on the framebuffer and then flushes its journal. The journal now
always has a reference on the framebuffer whenever it is non-empty.
That means the unref will only cause a flush if the only thing keeping
the framebuffer alive is the entries in the journal.

c6528c4b6c Start removing _EXP defines and improves some docs
Originally we decided to use #define tricks to rename all experimental
symbols so that they had an _EXP suffix so it would be a bit clearer for
those wanting to check for ABI changes that they shouldn't worry about
these experimental symbols.

We feel now though that the defines are a bit more hassle than they are
really worth, since they are one extra thing to remember when coding,
they make using gdb slightly more awkward since you have to use the real
symbol name to set breakpoints and we already have a mechanism for
declaring symbols as experimental via gtk-doc that can be used by anyone
wanting to check for ABI changes.

Instead of just using a script to remove all the #defines we are going
to go through them manually because we need to make sure the symbols
are marked as unstable via gtk-doc. This patch does a first batch of
define removals and in fact some of the symbols didn't have any
documentation at all so that needed to be added too.

descriptor of the X connection and it can manually handle the
events.

The event retrieval can be disabled by an application if it calls the

event retrieval will also automatically be disabled if the application

                    int *n_poll_fds,

                    const CoglPollFD *poll_fds,
                    int n_poll_fds);

The application is expected to call the first function whenever it is
about to block to go idle, and the second function whenever it comes
out of idle. This gives Cogl winsys's the ability poll file
descriptors for events. For example when handing swap complete
notifications, it can report that it needs to block on a file
descriptor.

The two functions are backed by winsys virtual functions. There are

616d27f169 cogl-texture-2d: Fix checking for the EGL winsys
CoglTexture2D had an assert to verify that the EGL winsys was being
used. This doesn't make any sense any more because the EGL winsys
can't be used directly but instead it is just a base winsys for the
platform winsys's. To fix this this patch adds a set of 'criteria'
flags to each winsys, one of which is 'uses EGL'. CoglTexture2D can
use this to determine if the winsys is supported.

Eventually we might want to expose these flags publically so that an
application can select a winsys based on certain conditions. For
example, an application may need a winsys that uses X or EGL but
doesn't care exactly which one it is.

more like an implementation detail that is specific to the winsys

f005f517fe Flush matrices in the progend and flip with a vector
Previously flushing the matrices was performed as part of the
framebuffer state. When on GLES2 this matrix flushing is actually
diverted so that it only keeps a reference to the intended matrix
stack. This is necessary because on GLES2 there are no builtin
uniforms so it can't actually flush the matrices until the program for
the pipeline is generated. When the matrices are flushed it would
store the age of modifications on the matrix stack so that it could
detect when the matrix hasn't changed and avoid flushing it.

This patch changes it so that the pipeline is responsible for flushing
the matrices even when we are using the GL builtins. The same
mechanism for detecting unmodified matrix stacks is used in all
cases. There is a new CoglMatrixStackCache type which is used to store
a reference to the intended matrix stack along with its last flushed
age. There are now two of these attached to the CoglContext to track
the flushed state for the global matrix builtins and also two for each
glsl progend program state to track the flushed state for a
program. The framebuffer matrix flush now just updates the intended
matrix stacks without actually trying to flush.

When a vertex snippet is attached to the pipeline, the GLSL vertend
will now avoid using the projection matrix to flip the rendering. This
is necessary because any vertex snippet may cause the projection
matrix not to be used. Instead the flip is done as a forced final step
by multiplying cogl_position_out by a vec4 uniform. This uniform is
updated as part of the progend pre_paint depending on whether the
framebuffer is offscreen or not.
