53f0861059 gl: Make _cairo_gl_shader_(init|compile) static 
Only used within _cairo_gl_shaders.c, so remove the private symbol.

dd0866cdc8 boilerplate: Exercise RENDER capable windows. 
Ensure that the drivers actually work when rendering to a normal window.

2f0f4ed0e2 freed-pool: Don't access beyond the end of the array. 
Argh. This bug has been here for quite some time and only showed itself
with a corrupt pointer on ppc32. Since the erroneous write is inside the
block, it remained undetected by valgrind.

24e684c267 gl: spans need the dummy texture 
Thanks Eric. That took me half a day.

d7a564d8ee gl: Don't set is_clear 
1) It's wrong.
2) The core functions set the flag correctly already.

f9cf07b126 gl: Fix coverage passing for spans not being endian safe. 2010-05-20 16:08:38 +02:00

1586f7740a gl: Refactor fixed function setup code 
In particular get rid of the _cairo_gl_set_tex_combine_constant_color()
function by inlining it and move common glTexEnv calls out of the
switch statement.

4889090c76 gl: set the active texture before fiddling with with glTexEnv 
fixes the fixed function pipeline

d9d5976bdf gl: Add an assertion that a context cannot call _begin() twice 
Evert _begin() call must be followed by an _end() call to avoid any
nastiness. Just like GL. :)

5b8b1fe1cb gl: Move vertex buffer handling from setup into context 
We can only emit one vertex buffer at a time anyway.

0d5f2eab77 gl: Actuall do fall back to fixed function paths. 
Previously we were just returning UNSUPPORTED all the time. I guess that
explains why my code got so slow...

bb7ca71c1a gl: Don't store the shader in the composite_t anymore 
Now that we have ctx->current_shader, there's no need to keep it in the
composite setup code.
 2010-05-20 11:02:49 +02:00
Benjamin Otte
6c477b4a94 gl: Move shader checking in the TexEnv setup code 
As the previously generic setup code only contains non-shader code now,
we can check in advance that no shader is in use and do all the other
stuff without checks.
 2010-05-20 11:02:49 +02:00
Benjamin Otte
73262edd82 gl: Move texture setup code into its own file 
This ensures textures don't need to be (re)set when doing component
alpha and running 2 shaders.

970c879dd8 gl: Binding variables only works for the current shader 
So make the code reflect that.
 2010-05-20 11:02:49 +02:00

065969d78f gl: Separate binding to shaders from setting operands 
That way we only need to bind to shaders when creating them, but not
everytime we switch shaders on text output.
 2010-05-20 11:02:49 +02:00

c53f7778bc gl: Use the mask, not the source 
Not that we'd ever have constant color component-alpha masks, but that's
an entirely different topic.
 2010-05-20 11:02:49 +02:00
Benjamin Otte
26e8e506b6 gl: Add _cairo_gl_surface_is_texture() 
It's more explicit then just checking surface->fb != 0
Also, it makes improving that check easier.
 2010-05-20 11:02:49 +02:00

e4cb46b500 gl: Implement texture upload to window with composite() 
Instead of custom code that does basically the same thing, use
a temporary surface and _cairo_gl_surface_composite() to upload images.

6864ca6c25 gl: Move _cairo_gl_set_operator() to the file it's used in 
Also make it a private function.

0d2d4c5902 gl: Detect color-pattern clears of surfaces 
... and use glClear() there.

The common case here is a solid color and OPERATOR_OVER.

915aa64ef0 gl: Actually check errors for _cairo_gl_composite_begin() 2010-05-20 11:01:21 +02:00

0222cc7d76 gl: Get rid of _cairo_gl_composite_set_mask_texture() 
Now that the glyph cache contains real surfaces, there's no longer a
need to have a special function for it.
 2010-05-20 11:01:19 +02:00
Benjamin Otte
208d9f2a7e gl: Make glyph cache a real surface 
This has the huge advantage that we can use real surface functions on
it.

0501179963 surface: Add _cairo_surface_release_device_reference() API 
See the API documentation for that function about its intended purpose.

c489f67d1d gl: Make a bunch of functions static 
They are no longer used outside of cairo_gl_composite_t.
 2010-05-18 13:43:27 +02:00

c8008e118a gl: Don't name the union in cairo_gl_operand_t 
Gets rid of ultra-long variable names.

53260148ea quartz: fix repeating radial gradients on 64 bits 
Quartz API uses the type CGFloat, which is double on 64 bits,
float on 32 bits architectures

0104976dc8 quartz: silence compiler warnings 
All the possible enum values have to be explicitly handled in switch statements.

ac94a00a4d quartz: fallback for A1 images on little endian archs 
Quartz uses a bit ordering that is consistent with cairo on big
endian architectures, but isn't on little endian architectures.

Fixes a1-mask and large-source-roi (on little endian)

<Error>: CGContextSetTextMatrix: invalid context 0x0
<Error>: CGContextSetAlpha: invalid context 0x0

1687e61694 quartz-font: Conform context and antialias handling to quartz-surface 
A8 surfaces are now kAlphaOnly surfaces in quartz-font too.
Subpixel font smoothing can be enabled.

d68bbc0fe5 gl: Add missing NULL-check in non-shader code 2010-05-17 20:57:08 +02:00
Benjamin Otte
7f22372edf gl: Get rid of src and mask argument to composite_init() 
This was thought of as a way to detect self-painting, but it's better to
check that later in _begin() - when we check it.
 2010-05-17 18:54:31 +02:00

75f15babed gl: Implement fill_rectangles with composite 
Tiny performance improvement, but a lot less code.

e7c5b4f79f gl: make _set_mask() accept NULL 
That way, it can be used to unset the mask.

145db7a427 gl: Check status after composite_begin 
Skip the unnecessary work in _cairo_gl_surface_composite() if we fail
to setup the GL composite operation.

8695c41e80 gl: Throw a _cairo_error when detecting a GLerror 
This allows us to easily set an breakpoint and inspect cairo's state
when we do something illegal.

1c18ab02c8 gl: Rename cairo_gl_shader_program_t to cairo_gl_shader_t 
And complete the move of the shaders into the cairo_gl_shader namespace.
Of particular note, the bind_*_to_shader become
_cairo_gl_shader_bind_*() and have proper types.
