Differences Between draw/push and write Functions

Unlike draw/push functions, write functions are not wrapped by startWrite and endWrite.
draw/push functions call startWrite and endWrite internally, which makes them slightly slower when executing many drawing operations consecutively. In such cases, execute all draw/push functions between a single startWrite and endWrite to improve speed.

draw/push and write Functions Table

write(read)	draw or push (etc)
writePixel	drawPixel
writePixels	pushPixels
writePixelsDMA	pushPixelsDMA
writeFastHLine	drawFastHLine
writeFastVLine	drawFastVLine
writeFillRect	fillRect
writeColor
pushBlock

Note:

pushBlock was not named writeBlock for library version compatibility.
