Subject: [PATCH] [rtextures] Fix ImageDrawCircle asymmetry (#6118)

ImageDrawCircle filled 2*radius pixels wide but 2*radius + 1 tall. Each
horizontal span started at centerX - x with width 2*x, which covers
centerX - x through centerX + x - 1, leaving the column at centerX + x
unwritten. The result was one column short on the right, off-centre, and
inconsistent with ImageDrawCircleLines, which is 2*radius + 1 in both
directions.

Widen the four spans by one pixel so the fill is (2r+1) x (2r+1), centred
on (centerX, centerY) and aligned with ImageDrawCircleLines.

Fixes #6117
