[Win] Support composited content in WebView render-to-context methods
https://bugs.webkit.org/show_bug.cgi?id=149516
<rdar://problem/22635080>
Reviewed by Simon Fraser.
Source/WebCore:
Extend the CACFLayerTreeHost implementation to render into a passed
device context when requested. When no context is provided (the default
case) paint as normal.
Will be tested by existing compositing tests in a future bug. DumpRenderTree
has to be extended to do this painting properly.
* platform/graphics/ca/win/CACFLayerTreeHost.cpp:
(WebCore::CACFLayerTreeHost::paint): Accept an optional HDC argument, and
pass it to the render method.
* platform/graphics/ca/win/CACFLayerTreeHost.h:
* platform/graphics/ca/win/LegacyCACFLayerTreeHost.cpp: Add missing SOFT_LINK
command for the WKCACFViewDrawIntoDC.
(WebCore::LegacyCACFLayerTreeHost::paint): Accept optional HDC argument and
pass it to the parent class.
(WebCore::LegacyCACFLayerTreeHost::render): Accept new optional HDC argument.
If provided, call WKCACFViewDrawIntoDC. Otherwise, call WKCACFVIewDraw.
* platform/graphics/ca/win/LegacyCACFLayerTreeHost.h:
* platform/graphics/ca/win/WKCACFViewLayerTreeHost.cpp: Add missing SOFT_LINK
command for the WKCACFViewDrawIntoDC.
(WebCore::WKCACFViewLayerTreeHost::paint): Accept optional HDC argument and
pass it to the parent class.
(WebCore::WKCACFViewLayerTreeHost::render): Accept new optional HDC argument.
If provided, call WKCACFViewDrawIntoDC. Otherwise, call WKCACFVIewDraw.
* platform/graphics/ca/win/WKCACFViewLayerTreeHost.h:
Source/WebKit/win:
* WebView.cpp:
(WebView::paint): Call the new 'paintCompositedContentToHDC' method. If
it handles the pain, return.
(WebView::paintCompositedContentToHDC): New method to share code with other
paint methods.
(WebView::paintDocumentRectToContext): Call new 'paintCompositedContentToHDC'
to handle any composited layers. Otherwise, use slow drawing path.
(WebView::paintScrollViewRectToContextAtPoint): Ditto.
(WebView::unused5): Work around a linker issue that may appear when building
test infrastructure on this branch.
* WebView.h:</pre>

+ [Win] Support composited content in WebView render-to-context methods
+ https://bugs.webkit.org/show_bug.cgi?id=149516
+ <rdar://problem/22635080>
+
+ Reviewed by Simon Fraser.
+
+ * WebView.cpp:
+ (WebView::paint): Call the new 'paintCompositedContentToHDC' method. If
+ it handles the pain, return.
+ (WebView::paintCompositedContentToHDC): New method to share code with other
+ paint methods.
+ (WebView::paintDocumentRectToContext): Call new 'paintCompositedContentToHDC'
+ to handle any composited layers. Otherwise, use slow drawing path.
+ (WebView::paintScrollViewRectToContextAtPoint): Ditto.
+ (WebView::unused5): Work around a linker issue that may appear when building
+ test infrastructure on this branch.
+ * WebView.h:
