shareable: Add Fill
...
Before introducing Fill, filling an image with a solid color was
implemented by ReplacePixels. When an offscreen image is used, the
offscreen image is not fully cleared or filled with a color and
out of (0,0)-(width,height) region. This causes a glitch thin line
on mobile platforms.
This change adds (*shareable.Image).Fill to fill the whole
framebuffer region of the image.

graphics: Speed up DrawTriangles ( #723 )
...
DrawTriangles is expensive and slow because of massive memory
allocation and garbage collection costs. This patch moves from ~47TPS
on my laptop (with ~24k triangles) to 60TPS. The first part
is just allocating the right size of vertex buffer up front; that
got to about 55TPS. The second part replaces the frequent
allocations of []float32 in Vertex() calls with writing the
desired values into a provided destination slice.
Time spent in drawing triangles for 1,000 frames:
13.07s baseline
11.09s preallocate whole buffer to avoid resizing
6.13s use new PutVertex function
This might need some cleanup, but I think it's good evidence that
the design change is viable.
