optional nit: We might want to rename these classes to match
transient_security_warning.h and permanent_security_warning.h.

ie. transient_security_warning_texture.h seems much more clear than
insecure_content_transient_texture.h (where the texture sounds transient).

Lets rename ALL the things.

Let's do this in a followup to avoid merge conflicts for now.

+class InsecureContentPermanentTexture : public UiTexture {
  public:
-  InsecureContentPermanentTexture(int texture_handle, int texture_size);
+  InsecureContentPermanentTexture();
   ~InsecureContentPermanentTexture() override;
+  gfx::Size GetPreferredTextureSize(int width) const override;
+  gfx::SizeF GetActualSize() const override;
 
  private:
-  void Draw(gfx::Canvas* canvas) override;
-  void SetSize() override;
+  void Draw(gfx::Canvas* canvas, const gfx::Size& texture_size) override;
 
-  int height_;
-  int width_;
+  gfx::SizeF size_;
 };
 
 }  // namespace vr_shell
 
 #endif  // CHROME_BROWSER_ANDROID_VR_SHELL_TEXTURES_INSECURE_CONTENT_PERMANENT_TEXTURE_H_
