Misaligned textures on south and east faces for non-full blocks

Description:

Texture on all non-full width non-symmetrical blocks on south and east sides are misaligned, like :

• Door

• trapdoor

• Fences

• Fencegates

• Wall

• Buttons

• Levers

• Stairs

• hopper

• Tripwire hook

This does not affect some blocks like cocoa, because they don't use the standard block method.

With that bug, it's very difficult to make HD texture pack since these details are near invisible with 16x packs but not on 64x packs for example.

Expected:

Having textures correctly aligned, like on Ax.png screenshots.

Actual:

Textures are misaligned, like on Bx.png screenshots.

Solution:

RenderBlocks.java

public class RenderBlocks {
    public void renderEastFace(Block par1Block, double par2, double par4, double par6, Icon texture) {
        Tessellator tessellator = Tessellator.instance;
        if (this.hasOverrideBlockTexture()) {
            texture = this.overrideBlockTexture;
        }
        /* START OF OLD CODE *
        double var10 = (double)texture.getInterpolatedU(this.renderMinX * 16.0D);
        double var12 = (double)texture.getInterpolatedU(this.renderMaxX * 16.0D);
        * END OF OLD CODE */
        /* START OF NEW CODE */
        double var10 = (double)texture.getInterpolatedU(16.0D - this.renderMaxX * 16.0D);
        double var12 = (double)texture.getInterpolatedU(16.0D - this.renderMinX * 16.0D);
        /* END OF NEW CODE */
        double var14 = (double)texture.getInterpolatedV(16.0D - this.renderMaxY * 16.0D);
        double var16 = (double)texture.getInterpolatedV(16.0D - this.renderMinY * 16.0D);
        /* ... */
    }
    public void renderSouthFace(Block par1Block, double par2, double par4, double par6, Icon texture) {
        Tessellator tessellator = Tessellator.instance;
        if (this.hasOverrideBlockTexture()) {
            texture = this.overrideBlockTexture;
        }
        /* START OF OLD CODE *
        double var10 = (double)texture.getInterpolatedU(this.renderMinZ * 16.0D);
        double var12 = (double)texture.getInterpolatedU(this.renderMaxZ * 16.0D);
        * END OF OLD CODE */
        /* START OF NEW CODE */
        double var10 = (double)texture.getInterpolatedU(16.0D - this.renderMaxZ * 16.0D);
        double var12 = (double)texture.getInterpolatedU(16.0D - this.renderMinZ * 16.0D);
        /* END OF NEW CODE */
        double var14 = (double)texture.getInterpolatedV(16.0D - this.renderMaxY * 16.0D);
        double var16 = (double)texture.getInterpolatedV(16.0D - this.renderMinY * 16.0D);
        /* ... */
    }
}
