Pixel-perfect doesn't work in Manual tile mode

[TaperingBirch]

Pixel-perfect is always off in manual tile mode, even if the toggle is turned on.

Reproduce:

1. Make a tilemap layer and a tileset, filled with whatever tiles(doesn't matter what, as long as they have some filled pixels in them, not completely transparent)
2. Place one tile from the tileset on the tilemap with space+tab or the button all the way on the left above the color palate
3. Switch to manual mode using the button above the color palate or space+1
4. Turn Pixel-perfect on
5. Draw a circle on top of a tile using the brush tool
6. The circle looks as if pixel-perfect was turned off
