tests: Test reading all pixel formats The test-read-alpha-texture test has been replaced with a test that tries reading an RGBA texture in all current pixel formats. On GLES2 this should end up testing all of the convesion code because in that case GL only supports reading back RGBA data. The test now works on GLES2 since the conversion code for all of the formats has been added so this also removes the GL requirement. Reviewed-by: Robert Bragg <robert@linux.intel.com>

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem.

Add support for RG textures This adds COGL_PIXEL_FORMAT_RG_88 and COGL_TEXTURE_COMPONENTS_RG in order to support two-component textures. The RG components for a texture is only supported if COGL_FEATURE_ID_TEXTURE_RG is advertised. This is only available on GL 3, GL 2 with the GL_ARB_texture_rg extension or GLES with the GL_EXT_texture_rg extension. The RG pixel format is always supported for images because Cogl can easily do the conversion if an application uses this format to upload to a texture with a different format. If an application tries to create an RG texture when the feature isn't supported then it will raise an error when the texture is allocated. https://bugzilla.gnome.org/show_bug.cgi?id=712830 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 568677ab3bcb62ababad1623be0d6b9b117d0a26) Conflicts: cogl/cogl-bitmap-packing.h cogl/cogl-types.h cogl/driver/gl/gl/cogl-driver-gl.c tests/conform/test-read-texture-formats.c tests/conform/test-write-texture-formats.c

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

Adds cogl_framebuffer_draw_[*_]rectangle functions This adds experimental 2.0 api replacements for the cogl_rectangle[_*] functions that don't depend on having a current pipeline set on the context via cogl_{set,push}_source() or having a current framebuffer set on the context via cogl_push_framebuffer(). The aim for 2.0 is to switch away from having a statefull context that affects drawing to having framebuffer drawing apis that are explicitly passed a framebuffer and pipeline. To test this change several of the conformance tests were updated to use this api instead of cogl_rectangle and cogl_rectangle_with_texture_coords. Since it's quite laborious going through all of the conformance tests the opportunity was taken to make other clean ups in the conformance tests to replace other uses of 1.x api with experimental 2.0 api so long as that didn't affect what was being tested.

Add support for RG textures This adds COGL_PIXEL_FORMAT_RG_88 and COGL_TEXTURE_COMPONENTS_RG in order to support two-component textures. The RG components for a texture is only supported if COGL_FEATURE_ID_TEXTURE_RG is advertised. This is only available on GL 3, GL 2 with the GL_ARB_texture_rg extension or GLES with the GL_EXT_texture_rg extension. The RG pixel format is always supported for images because Cogl can easily do the conversion if an application uses this format to upload to a texture with a different format. If an application tries to create an RG texture when the feature isn't supported then it will raise an error when the texture is allocated. https://bugzilla.gnome.org/show_bug.cgi?id=712830 Reviewed-by: Robert Bragg <robert@linux.intel.com> (cherry picked from commit 568677ab3bcb62ababad1623be0d6b9b117d0a26) Conflicts: cogl/cogl-bitmap-packing.h cogl/cogl-types.h cogl/driver/gl/gl/cogl-driver-gl.c tests/conform/test-read-texture-formats.c tests/conform/test-write-texture-formats.c
