* Reverting 20516 by re-landing this previous patch.brettw@chromium.org2009-07-171-1/+1
| | | | | | | | | | | | | Keep the cairo clipping region in sync with the Skia one. The PlatformCanvas now tracks this, so we don't need to have the similar code in gfx::Canvas. I moved most references of cairo_surface_t to cairo_t since the cairo_t has a transform and clip but the surface does not.

* Refactor the PlatformContext layer to have only one class.brettw@chromium.org2009-06-141-41/+18
| | | | | | | | | | | | | | | | | | | | | | | | | Previously we had three classes of PlatformCanvas*, one for each platform. Then we had a typedef of PlatformContext to PlatformCanvas[Mac|Win|Linux] for the specific platform. This means that it was almost impossible to forward-declare PlatformCanvas and there were a bunch of unnecessary includes of platform_canvas.h in header files. This change makes there be only one platform_canvas.h header with ifdefs, which removes a decent amount of duplicated code. There is a platform-independent file, and one platform-dependent file of platform_canvas for each platform. I also renamed PlatformDevice[Mac|Win|Linux] to PlatformDevice, althouth in this case I kept the separate headers since there was much less overlap. I also broke out CanvasPaint into separate headers so this template doesn't need to be included all over the project (only a couple of files actually need it).

* Basic windowless plugins, try 2.evan@chromium.org2009-03-131-0/+4
| | | | | | | | | | | In response to Dean's comment on http://codereview.chromium.org/39105, I redid that patch to put the X munging into the plugin implementation. This won't work for multiproc, but it's near the correct place and many things will need to be changed for multiproc.

* Bitmap transportagl@chromium.org2009-02-201-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks bitmap transport on all platforms. Linux and Mac are switched from serialising bitmaps over the IPC channel to using shared memory. All platforms gain a shared memory mapping cache on the host side. The concept of a TransportDIB (device independent bitmap) is added to encapsulate most of the platform specifics. On Linux, we use SysV shared memory. This is because X shared pixmaps, which predate POSIX SHM, can only use SysV. By using SysV between renderer and browser, we open up the possibility to map the shared memory directly from the renderer to the X server. On Mac, we use POSIX shared memory. However, since this needs filesystem access and the Mac renderer is sandboxed from the filesystem, we add two new messages from renderer -> browser: The first, AllocTransportDIB, synchronously creates a transport DIB in the browser and passes a handle back to the renderer. The second, FreeTransportDIB, asynchronously, notifies the browser that it may close its handle to the shared memory region. On Mac, the shared memory regions are identified by their inode numbers on the wire. This means that the browser must keep handles open to all the allocated shared memory regions (since an inode number is insufficient to map the region). The alternative design is that the renderer passes the file descriptor with each paint operation. Since passing file descriptors is special case in the code, I felt that it would be best to minimise their use. Creating and freeing transport DIBs are relatively rare operations relative to paints and scrolls. On Windows, most of the code remains the same, except that Windows now uses the mapping cache added in this patch. This allows the browser to maintain a shared memory mapping for a transport DIB over several paints. Previously it mapped and unmapped for every operation, causing lots of TLB and VM churn.
