<h3>Log Message</h3>
<pre>[iOS] ResourceUsageOverlay should work on iOS.
<https://webkit.org/b/152021>
Reviewed by Antti Koivisto.
Source/WebCore:
Make ResourceUsageOverlay work on iOS and on Mac desktops with UI-side compositing.
* page/ResourceUsageOverlay.cpp:
(WebCore::ResourceUsageOverlay::initialize): Move the overlay to the top of the view on iOS for now.
* page/ResourceUsageOverlay.h:
* page/cocoa/ResourceUsageOverlayCocoa.mm:
(WebCore::createColor): Make a custom CGColor factory since we can't use CGColorCreateGenericRGB on iOS.
(WebCore::MemoryCategoryInfo::MemoryCategoryInfo):
(WebCore::ResourceUsageOverlay::platformInitialize): Put the overlay CALayer into a container layer and
hook it up with GraphicsLayer::setContentsToPlatformLayer so it works with all compositing modes.
(WebCore::showText): Move CGContextSaveGState call to the top of the function to preserve everything.
(WebCore::drawGraphLabel):
(WebCore::drawCpuHistory):
(WebCore::drawGCHistory):
(WebCore::ResourceUsageOverlay::platformDraw): Flip the CGContext if needed.
(WebCore::runSamplerThread): Update the layer rects on each thread iteration. This shouldn't be
necessary but it papers over an issue where the containing layer would shrink down to 0x0 and
disappear. Added a FIXME for this.
* platform/spi/cocoa/MachVMSPI.h: Add purgeable VM SPI.
Source/WTF:
* wtf/Platform.h: Enable RESOURCE_USAGE_OVERLAY for all COCOA platforms.</pre>
