Draws a partial arc of an oval.

Parameters

paint	describes how to color pixels.
GrGrAA	Controls whether the arc is antialiased.
viewMatrix	transformation matrix.
oval	the bounding rect of the oval.
startAngle	starting angle in degrees.
sweepAngle	angle to sweep in degrees. Must be in (-360, 360)
useCenter	true means that the implied path begins at the oval center, connects as a line to the point indicated by the start contains the arc indicated by the sweep angle. If false the line beginning at the center point is omitted.
style	style to apply to the oval.

Variant of drawTexture that instead draws the texture applied to 'dstQuad' transformed by 'viewMatrix', using the 'srcQuad' texture coordinates clamped to the optional 'subset'. If 'subset' is null, it's equivalent to using the fast src rect constraint. If 'subset' is provided, the strict src rect constraint is applied using 'subset'.

	)

Draws a set of textures with a shared filter, color, view matrix, color xform, and texture color xform. The textures must all have the same GrTextureType and GrConfig.

If any entries provide a non-null fDstClip array, it will be read from immediately based on fDstClipCount, so the pointer can become invalid after this returns.

'proxRunCnt' is the number of proxy changes encountered in the entry array. Technically this can be inferred from the array within this function, but the information is already known by SkGpuDevice, so no need to incur another iteration over the array.

inline

Similar to fillRectWithEdgeAA but draws an arbitrary 2D convex quadrilateral transformed by 'viewMatrix', with per-edge control over anti-aliasing. The quad should follow the ordering used by SkRect::toQuad(), which determines how the edge AA is applied:

"top" = points [0] and [1]
"right" = points[1] and [2]
"bottom" = points[2] and [3]
"left" = points[3] and [0]

The last argument, 'optionalLocalQuad', can be null if no separate local coordinates are necessary.
