Merge lp:compiz-core/gles into lp:compiz-core/0.9.8

[Sam Spilsbury]

This branch contains the code to make compiz work on GLES. This includes several changes to the compiz API.

* GLVertexBuffer class added for managing vertices, normals, texture coordinates, and colors
* GLProgram class added for managing GLSL programs
* GLProgramCache class added for managing per-plugin GLSL programs efficiently, uses an LRU cache
  to avoid recompiling recently used GLSL programs all the time
* GLShaderCache class added for managing dynamically created shader source code.
* GLFragment class removed as fragment programs are no longer used (replaced with GLSL programs)
* EGL context setup added
* EglTexture class added to use EGL_image extension instead of GLX_EXT_texture_from_pixmap for GLES

TODO:

 * Port Blur Plugin (Bug 999018)
 * Port Cube Plugin (Bug 999017)
   - Support vertex clipping (see commented code in glEnableOutputClipping -
   - Support proper texture modulation for transparency
   - Change GL_QUADS usage in skybox vertex assembly to GL_TRIANGLE usage
 * Implement VSync support in EGL codepath: DONE
 * Write internal porting guide from GLES to GL
 * Push this branch to a testing PPA for Q
 * Keep list of regressions up to date and verify with distro
 * Write up testing strategy document

[Alan Griffiths (alan-griffiths)]

Apart from a few (mostly simple) merge conflicts this builds with trunk. Unsurprisingly the unit tests pass (they don't touch the affected codepath).

Apart from a lack of the usual plugins the result runs.

[Omer Akram (om26er)]

make seems to fail on me http://paste.ubuntu.com/987280/ am I doing something wrong?

[Sam Spilsbury (smspillaz)]

Different compiler options most likely, cool that GCC is now catching deleting subclassed objects for which the base has a nonvirtual destructor

[Sam Spilsbury (smspillaz)]

@om26er: that compiler error should be fixed ... lets hope there are not other base classes with NVDs lying around ...

[Omer Akram (om26er)]

thanks, builds fine now. Still figuring how to make it start though ;-)

[Sam Spilsbury (smspillaz)]

Code wise, I feel like GLVertexBuffer's begin () and end () API's are a tad clunky, and exist really because GLVertexBuffer::streamingBuffer () does. We should look into removing this singleton and passing GLVertexBuffer objects directly to GLWindow::glAddGeometry () and GLWindow::glDrawGeometry ()

[Daniel van Vugt (vanvugt)]

WARNING:

The diff Launchpad is showing here is completely wrong. It's showing some identical files as changed and failing to show others that are very different (e.g. the water plugin).

I recommend diff'ing the branches manually to get a more realistic idea.

[Daniel van Vugt (vanvugt)]

The target branch lp:compiz-core is now retired. I will try to resubmit for: lp:compiz/0.9.8

review: Needs Resubmitting

[Daniel van Vugt (vanvugt)]

Please look at this proposal instead:

Unmerged revisions

3150. By Daniel van Vugt on 2012-05-16

Fixed water lighting calculations (LP: #1000097)
 - Normals were inside-out as I predicted.
 - Slightly simplified the shader code.
 - Use all 3 dimensions of the lighting vector, not just 2.
 - Increased the offset scale (diffraction effect) to look like the old code.
 - Reversed lighting vector X component to look like the old code..
 - Set lighting vector Z component to zero to avoid lighting whole screen.

3149. By Daniel van Vugt on 2012-05-16

Fix annotate turning display completely black (LP: #1000093)

3148. By Daniel van Vugt on 2012-05-15

plugins/opengl/src/screen.cpp: Delete an outdated comment and deduplicate
another.

3147. By Daniel van Vugt on 2012-05-15

Rebase on lp:compiz-core r3137

3146. By Sam Spilsbury on 2012-05-14

Give AutoProgram a virtual destructor and move it into a namespace.

Nested classes and nonvirtual destructors on abstract classes are evil.

3145. By Sam Spilsbury on 2012-05-14

Start implementing eglSwapBuffers in the paint dispatch. Removed a useless functor check

3144. By Sam Spilsbury on 2012-05-14

Remove useless spew

3143. By Sam Spilsbury on 2012-05-14

GL_TEXTURE_COORD_ARRAY client state setting is not necessary because its done implicitly
when binding OpenGL buffer objects.

Disable output clipping, skybox and texture modulation on GLES2 for now

3142. By Sam Spilsbury on 2012-05-14

Clip planes aren't yet supported on GLES .. remove glNormal* usage

3141. By Sam Spilsbury on 2012-05-14

Port the bottom cap renderer to GLES.

Since both caps use the same vertex array with GL_TRIANGLE_FAN ... a rather unsatisfactory
workaround was added to GLVertexBuffer to control the behaviour of glDrawArrays ... worth looking
into removing
