75226501cf Don't use cogl_get_draw_framebuffer when flushing pipeline state
Some of the state when flushing a pipeline depends on the current
framebuffer being used. These are:

• The matrix stack, so that it can flip vertically or not depending on
  whether the framebuffer is offscreen.
• The colormask. This is combined with the framebuffer's color mask.
• The cull face mode. If the framebuffer is offscreen then backface
  culling is translated to frontface culling and vice-versa.

These states were not working if the new framebuffer draw_primitive
API was used because in that case the framebuffer is not pushed to the
framebuffer stack so it would use the wrong one. This patch changes it
to use ctx->current_draw_buffer which is a pointer to the framebuffer
whose state was last flushed.

3700cc26a5 Change API so that CoglPixelBuffer no longer knows its w/h/format
The idea is that CoglPixelBuffer should just be a buffer that can be
used for pixel data and it has no idea about the details of any images
that are stored in it. This is analogous to CoglAttributeBuffer which
itself does not have any information about the attributes. When you
want to use a pixel buffer you should create a CoglBitmap which points
to a region of the attribute buffer and provides the extra needed
information such as the width, height and format. That way it is also
possible to use a single CoglPixelBuffer with multiple bitmaps.

The changes that are made are:

• cogl_pixel_buffer_new_with_size has been removed and in its place is
  cogl_bitmap_new_with_size. This will create a pixel buffer at the
  right size and rowstride for the given width/height/format and
  immediately create a single CoglBitmap to point into it. The old
  function had an out-parameter for the stride of the image but with
  the new API this should be queriable from the bitmap (although there
  is no function for this yet).

• There is now a public cogl_pixel_buffer_new constructor. This takes
  a size in bytes and data pointer similarly to
  cogl_attribute_buffer_new.

• cogl_texture_new_from_buffer has been removed. If you want to create
  a texture from a pixel buffer you should wrap it up in a bitmap
  first. There is already API to create a texture from a bitmap.

This patch also does a bit of header juggling because cogl-context.h
was including cogl-texture.h and cogl-framebuffer.h which were causing
some circular dependencies when cogl-bitmap.h includes cogl-context.h.
These weren't actually needed in cogl-context.h itself but a few other
headers were relying on them being included so this adds the #includes
where necessary.

10a38bb14f Add a public cogl_framebuffer_read_pixels_into_bitmap
This adds a public function to read pixels from a framebuffer into a
CoglBitmap. This replaces the internal function
_cogl_read_pixels_with_rowstride because a CoglBitmap contains a
rowstride so it can be used for the same purpose. A CoglBitmap already
has public API to make one that points to a CoglPixelBuffer so this
function can be used to read pixels into a PBO. It also avoids the
need to push the framebuffer on to the context's stack so it provides
a function which can be used in the 2.0 API after the stack is
removed.

2501899044 cogl-buffer: Create the buffer store when bound
Whenever the buffer is bound with _cogl_buffer_bind Cogl now ensures
the buffer's data store has been created. Previously it would only
ensure it was created when it was first mapped or when the first data
was set on it. This is necessary if we are going to use CoglBuffers
for retrieving data from GL. In that case the buffer won't be mapped
or have data set on it before it is used.

f4cd5aceb9 _cogl_bitmap_convert: Also handle premult conversions
If we are going to unpack the data into a known format anyway we might
as well do the premult conversion instead of delaying it to do
in-place. This helps because not all formats with alpha channels are
handled by the in-place premult conversion code. This removes the
_cogl_bitmap_convert_format_and_premult function so that now
_cogl_bitmap_convert is a completely general purpose function that can
convert from anything to anything. _cogl_bitmap_convert now includes a
fast path for when the base formats are the same and the premult
conversion can be handled with the in-place code so that we don't need
to unpack and can just copy the bitmap instead.

8ce5f5ade8 bitmap: Remove the split between 'image library' and 'fallback'
Previously the bitmap code was setup so that there could be an image
library used to convert between formats and then some 'fallback' code
when the image library can't handle the conversion. However there was
never any implementation of the conversion in the image library so the
fallback was always used. I don't think this split really makes sense
so this patch renames cogl-bitmap-fallback to cogl-bitmap-conversion
and removes the stub conversion functions in the image library.

908ba29be5 bitmap-fallback: Support converting all pixel format types
_cogl_bitmap_fallback_convert now supports converting to and from all
of the pixel formats, except it continues to preserve the premult
status of the original bitmap. The pixels are unpacked into a
temporary buffer that is either 8-bits per component or 16-bits per
component RGBA depending on whether the destination format is going to
use more than 8 bits per component (eg RGBA_1010102). The packing and
unpacking code is stored in a separate header which is included twice
to generate the functions needed for both sizes of unpacked data. The
hope is that when converting between two formats that are both 8-bit
sized, such as swizzling between BGRA and RGBA, then the
multiplications and divisions in the code will be optimized out and it
shouldn't be too inefficient. Previously the inner switch statement to
decide which conversion to use only operated on one pixel at a time so
it was probably relatively slow.

323adc0c14 Avoid making up the format COGL_PIXEL_FORMAT_A_8_PRE
There are a few places in Cogl that try to set the premult bit on a
pixel format depending on whether it has an alpha channel. However
this breaks if the pixel format is alpha-only because premultiplying
data without any RGB components doesn't make any sense. This adds an
internal macro to check for cases where we should add the premult bit
called COGL_PIXEL_FORMAT_CAN_HAVE_PREMULT. This now gets used in all
places that previously just checking for COGL_A_BIT.

bbcbece6c9 tests: Improve thoroughness and reporting of make test
This patch reworks our conformance testing framework because it seems
that glib's gtesting framework isn't really well suited to our use case.
For example we weren't able to test windows builds given the way we
were using it and also for each test we'd like to repeat the test
with several different environments so we can test important driver and
feature combinations.

This patch instead switches away to a simplified but custom approach for
running our unit tests. We hope that having a more bespoke setup will
enable us to easily extend it to focus on the details important to us.

Notable changes with this new approach are:

We can now run 'make test' for our mingw windows builds.

We've got rid of all the test-*report* make rules and we're just left
with 'make test'

'make test' now runs each test several times with different driver and
feature combinations checking the result for each run. 'make test' will
then output a concise table of all of the results.

The combinations tested are:
- OpenGL Fixed Function
- OpenGL ARBfp
- OpenGL GLSL
- OpenGL No NPOT texture support
- OpenGLES 2.0
- OpenGLES 2.0 No NPOT texture support

39c6bf59cb texture: Handle premult conversions when getting texture data
cogl_texture_get_data uses find_best_gl_get_data_format from the
texture driver which returns the closest format to use for retrieving
pixel data given an intended format. However this function doesn't
know about the texture we are reading data from so it doesn't know
that the data we will actually receive will have the same premult
status as the texture's format. With the GL driver, this function ends
up returning exactly the same format as passed in which means it will
never do a premult conversion. Under GLES it always returns
COGL_PIXEL_FORMAT_RGBA_8888 so it will always make the data unpremult
even if the final requested format is premultiplied.

This patch fixes it so that it copies the premult status of the
closest_format from the format of the underlying texture. That way it
will later convert or not depending on the requested target format.

Note this patch breaks test-sub-texture with the GL driver because
that is incorrectly trying to read the texture data back as RGBA_8888
even though it depends on it not doing a premult conversion. The test
was already broken with GLES2 and remains broken.
