Improve blacklist logic: use more fields (driver_vendor, gl_renderer, ect) fo...

chrome/browser/resources/gpu_blacklist.json

+// Determines whether certain gpu-related features are blacklisted or not.
+// A valid gpu_blacklist.json file are in the format of
+// {
+//   "version": "x.y",
+//   "entries": [
+//     { // entry 1
+//     },
+//     ...
+//     { // entry n
+//     }
+//   ]
+// }
+//
+// Each entry contains the following fields:
+// "os", "vendor_id", "device_id", "driver_version", and "blacklist".
+// Only "blacklist" is mandatory.
+// 1. "os" contains "type" and an optional "version". "type" could be "macosx",
+//    "linux", "win", or "any".  "any" is the same as not specifying "os".
+//    "version" is a VERSION structure (defined below).
+// 2. "vendor_id" has the value of a string.
+// 3. "device_id" has the value of a string.
+// 4. "driver_vendor" is a STRING structure (defined below).
+// 5. "driver_version" is a VERSION structure (defined below).
+// 6. "gl_renderer" is a STRING structure (defined below).
+// 7. "blacklist" is a list of gpu feature strings, valid values include
+//    "accelerated_2d_canvas", "accelerated_compositing", "webgl", and "all".
+//    Currently whatever feature is selected, the effect is the same as "all",
+//    i.e., it's not supported to turn off one GPU feature and not the others.
+//
+// VERSION includes "op" "number", and "number2".  "op" can be any of the
+// following values: "=", "<", "<=", ">", ">=", "any", "between".  "number2" is
+// only used if "op" is "between".  "number" is used for all "op" values except
+// "any". "number" and "number2" are in the format of x, x.x, x.x.x, ect.
+//
+// STRING includes "op" and "value".  "op" can be any of the following values:
+// "contains", "beginwith", "endwith", "=".  "value" is a string.
