+ InstancedArray crashes attempting to draw out of bounds
+ https://bugs.webkit.org/show_bug.cgi?id=139521
+
+ Reviewed by Simon Fraser.
+
+ We were not doing index validation correctly for instancing.
+
+ Test: fast/canvas/webgl/angle-instanced-arrays-out-of-bounds.html
+
+ * html/canvas/WebGLRenderingContext.cpp:
+ (WebCore::WebGLRenderingContext::validateVertexAttributes): We need to check
+ the number of instances drawn against the amount of instance data that has
+ been provided, taking into account the number of repeats (the divisor).
+ (WebCore::WebGLRenderingContext::drawArrays): Added some whitespace to make it more clear.
+ (WebCore::WebGLRenderingContext::validateDrawElements): This needs to take a primcount
+ parameter so that it can correctly validate the call (when used from drawElementsInstanced).
+ (WebCore::WebGLRenderingContext::drawElements): New signature to validate.
+ (WebCore::WebGLRenderingContext::drawArraysInstanced): Rearrange this a bit. The
+ primcount validation is already being done by the validateDrawArrays call. Also, there
+ was a bogus UNUSED_PARAM hanging around.
+ (WebCore::WebGLRenderingContext::drawElementsInstanced): Similar rearrangement. Use
+ the primcount parameter.
+ * html/canvas/WebGLRenderingContext.h:
