| | | | | | | | | | | | | | Added a program argument so that at least in debug we can verify locations are correct. It also means we could fallback to actually calling GetUniformLocation if need be.

| | | | | | | | | | | | | | | | GL_CHROMIUM_copy_texture command buffer GL extension. The extension needs to support the ability to unpremultiply the source of the copy because of the canvas2d-webgl texture use case. Canvas is stored in premultiplied form, yet WebGL expects texture contents to be in unpremultiplied form. Change also includes conversion of argument types to overriders of WebGraphicsContext3D::copyTextureCHROMIUM(...).

The tests uncovered state that was not being properly restored: GL_BLEND. This is also corrected.

* Allow textures to be moved from one GL context group to another.apatrick@chromium.org2012-05-011-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | The function glProduceTexture(target, mailbox) removes a texture from a context group and puts it in a "mailbox" that is accessible to all context groups on the same channel. Then glConsumeTexture(target, mailbox) adds the texture to a context group, possibly a different one, if the caller knows the name of the mailbox. From the point of view of the caller, the texture objects themselves do not move, just the texels. In terms of the underlying GL, the TextureInfo service IDs are reassigned as necessary. A texture in a mailbox is destroyed when the context group that put it there is destroyed. Expected usage is: // Context 1 glBindTexture(GL_TEXTURE_2D, foo); glProduceTexture(GL_TEXTURE_2D, secret_name); glFlush(); // Context 2 glBindTexture(GL_TEXTURE_2D, bar); glConsumeTexture(GL_TEXTURE_2D, secret_name); Review URL: http://codereview.chromium.org/10106015 git-svn-id: svn://svn.chromium.org/chrome/trunk/src@134791 0039d316-1c4b-4281-b951-d872f2087c98

| | | | | | | | | | | | | | | | | | | | | | | | | This version corrects the problem that caussed the revert of the above issue. The shaders used by the extension were specifying a precision, which is not supported on desktop GL. The shaders now conditionally specify the precision. ------------------------------------------------------ Introduction of CHROMIUM_copy_texture extension that respects pixel-store semantics, and allows copying of BGRA textures. OpenGL ES does not natively allow for copying textures with a BGRA format. The EXT_texture_format_BGRA8888 extension does not specify support for glCopyTexImage calls on these textures. This extension provides a routine to perform texture copies to/from BGRA-backed textures that also respects the following CHROMIUM pixel storage modifiers: UNPACK_FLIP_Y_CHROMIUM UNPACK_PREMULTIPLY_ALPHA_CHROMIUM This extension will be useful for the following purposes: - Copying accelerated Canvas2D contents to WebGL textures without a software readback. (And potentially the same for video-webgl texture copies.) - Copying Canvas2D contents to the compositor backing store.
