cogl-clip-state: Adapt to experimental cogl2 API. The current clip state implementation couldn't be used in conjunction with the CoglPath experimental API. http://bugzilla.clutter-project.org/show_bug.cgi?id=2594 Signed-off-by: Neil Roberts <neil@linux.intel.com>

cogl: rename cogl-context.h cogl-context-private.h Since we plan to add public cogl_context_* API we need to rename the current cogl-context.h which contains private member details.

cogl-clip-state: Export transform_point internally to Cogl The transform_point function takes a modelview matrix, projection matrix and a viewport and performs all three transformations on a point to give a Cogl window coordinate. This is useful in a number of places in Cogl so this patch moves it to cogl.c and adds it to cogl-internal.h

#include "cogl-matrix-private.h"
Add -Wmissing-declarations to maintainer flags and fix problems This option to GCC makes it give a warning whenever a global function is defined without a declaration. This should catch cases were we've defined a function but forgot to put it in a header. In that case it is either only used within one file so we should make it static or we should declare it in a header. The following changes where made to fix problems: • Some functions were made static • cogl-path.h (the one containing the 1.0 API) was split into two files, one defining the functions and one defining the enums so that cogl-path.c can include the enum and function declarations from the 2.0 API as well as the function declarations from the 1.0 API. • cogl2-clip-state has been removed. This only had one experimental function called cogl_clip_push_from_path but as this is unstable we might as well remove it favour of the equivalent cogl_framebuffer_* API. • The GLX, SDL and WGL winsys's now have a private header to define their get_vtable function instead of directly declaring in the C file where it is called. • All places that were calling COGL_OBJECT_DEFINE need to have the cogl_is_whatever function declared so these have been added either as a public function or in a private header. • Some files that were not including the header containing their function declarations have been fixed to do so. • Any unused error quark functions have been removed. If we later want them we should add them back one by one and add a declaration for them in a header. • _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and made a public function with a declaration in cogl-framebuffer.h • Similarly for CoglOnscreen. • cogl_vdraw_indexed_attributes is called cogl_framebuffer_vdraw_indexed_attributes in the header. The definition has been changed to match the header. • cogl_index_buffer_allocate has been removed. This had no declaration and I'm not sure what it's supposed to do. • CoglJournal has been changed to use the internal CoglObject macro so that it won't define an exported cogl_is_journal symbol. • The _cogl_blah_pointer_from_handle functions have been removed. CoglHandle isn't used much anymore anyway and in the few places where it is used I think it's safe to just use the implicit cast from void* to the right type. • The test-utils.h header for the conformance tests explicitly disables the -Wmissing-declaration option using a pragma because all of the tests declare their main function without a header. Any mistakes relating to missing declarations aren't really important for the tests. • cogl_quaternion_init_from_quaternion and init_from_matrix have been given declarations in cogl-quaternion.h Reviewed-by: Robert Bragg <robert@linux.intel.com>

Separate out CoglPath api into sub-library This splits out the cogl_path_ api into a separate cogl-path sub-library like cogl-pango and cogl-gst. This enables developers to build Cogl with this sub-library disabled if they don't need it which can be useful when its important to keep the size of an application and its dependencies down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path have been renamed to cogl_path_{fill,stroke}. There were a few places in core cogl and cogl-gst that referenced the CoglPath api and these have been decoupled by using the CoglPrimitive api instead. In the case of cogl_framebuffer_push_path_clip() the core clip stack no longer accepts path clips directly but it's now possible to get a CoglPrimitive for the fill of a path and so the implementation of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as a shim that first gets a CoglPrimitive and uses cogl_framebuffer_push_primitive_clip instead. We may want to consider renaming cogl_framebuffer_push_path_clip to put it in the cogl_path_ namespace. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 8aadfd829239534fb4ec8255cdea813d698c5a3f) So as to avoid breaking the 1.x API or even the ABI since we are quite late in the 1.16 development cycle the patch was modified to build cogl-path as a noinst_LTLIBRARY before building cogl and link the code directly into libcogl.so as it was previously. This way we can wait until the start of the 1.18 cycle before splitting the code into a separate libcogl-path.so. This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid breaking the 1.x API/ABI.

Remove all internal includes of cogl.h The cogl.h header is meant to be the public header for including the 1.x api used by Clutter so we should stop using that as a convenient way to include all likely prototypes and typedefs. Actually we already do a good job of listing the specific headers we depend on in each of the .c files we have so mostly this patch just strip out the redundant includes for cogl.h with a few fixups where that broke the build.

clip: Adds cogl_clip_push_primitive API This adds a new experimental function, cogl_clip_push_primitive, that allows you to push a CoglPrimitive onto the clip stack. The primitive should describe a flat 2D shape and the geometry shouldn't include any self intersections. When pushing a primitive you also need to tell Cogl what the bounding box of that shape is (in shape local coordinates) so that Cogl is able to efficiently update the required region of the stencil buffer.

Removes all remaining use of CoglHandle Removing CoglHandle has been an on going goal for quite a long time now and finally this patch removes the last remaining uses of the CoglHandle type and the cogl_handle_ apis. Since the big remaining users of CoglHandle were the cogl_program_ and cogl_shader_ apis which have replaced with the CoglSnippets api this patch removes both of these apis. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0) Since the original patch was done after removing deprecated API this back ported patch doesn't affect deprecated API and so actually this cherry-pick doesn't remove all remaining use of CoglHandle as it did for the master branch of Cogl.

CoglClipStack *stack;
framebuffer: Add CoglFramebuffer clip stack methods This adds CoglFramebuffer methods for accessing the clip stack. We plan on making some optimizations to how framebuffer state is flushed which will require us to track when a framebuffer's clip state has changed. This api also ties in to the longer term goal of removing the need for a default global CoglContext since these methods are all implicitly related to a specific context via their framebuffer argument.
